I keep getting this error message, no matter what server I try to join. I can log in just fine with the vanilla launcher. Any ideas?

there's a last login file in your .minecraft directory

if you delete it, the login is gone

EDIT:

The launcher isn't able to "launch" Minecraft 1.11.2 anymore with Nvidia's newest driver: 378.49

The official launcher still works fine though :/

No one can help , if you don't provide details . Java version , etc ... . Here are some fast facts about Magic Launcher .

1 , You must have a fully functional vanilla Minecraft .
2 , You must have Oracle Java 1.8 current build installed , ML will not ! , use Minecrafts java installation .
3 , ML will not update Minecraft , you must run the vanilla launcher from time to time to install Minecraft updates

4 , To play online , you must have a valid Minecraft Token downloaded using the vanilla launcher

Number 3 is my only gripe about this launcher. I hate the vanilla launcher so grrrrr much. I hade to make a demo account just so i dont have to input all of my info every time i want to update minecraft. Oh and i dont understand number 4. what does that mean.

The security Token is downloaded and stored in Minecrafts root directory . if your login ID and password is checked as authentic by Mojang/Microsoft servers , the server sends a Token . When you go online and login to a Forge or Spigot server , your Token must match a Server Token recieved from Mojang/Microsoft saying your a premiun player (bought the game) . This Token can be invalidated if you or someone else uses your account on another computer , then you're asked to login again . ML can not do any of this . It is outdated and was created to inject core mods into the Minecraft.jar .
Minecrafts new launcher has ideas from ML and MultiMC launcher . ML is still great for pre 1.7 modding , using Mod Loader and core mods

Seeing as the new Minecraft Launcher is able to run without an independent installation of Java, is that functionality ever going to be ported to Magic Launcher? If I can ditch another thing on my computer it would be nice, but in the end it really doesn't affect much.

Also curious to see if you would be able to/interested in adding more spaces for news. There are now more developers working on the game, so if they ever do tweet anything having all the news in one place would be nice. If not, having the ability to add news feed in manually would be a great alternative.

Love the launcher! Thank you for all the work you put into it on top of arguably the most important Minecraft mod out there!

I had the same problem with 378.49. I just upgraded to 378.66, released 13 February, and Magic Launcher works again for me. Very strange, never had that happen before.

You asked the same thing before . The question was answered many times as well .
ML is like the swiss army knife of mods . It can be used with all versions of Minecraft , below is the 1 example using Optifine

Optifine can be loaded in 3 ways
1 . A standalone install by double clicking Optifine installer . This creates a profile that can be loaded into ML
2. Put mods , in this case Optifine , in ..... > .mincraft / mods / version# / , where version# = the minecraft version . example version# = 1.10.2
now mods can be loaded via a Forge Profile , into ML . You need only add the Forge profile to ML , and nothing else
3. Same as 2. , but loaded via a litemod Profile , into ML

DONT ADD MODS to the mods window TAB , UNLESS it's a COREMOD or PRE 1.7 version coremod that requires the ancient modloader

If your not grasping the concept YouTube has many video's how this works

I have done this for both optifine and forge (ie minecraft/mods/1.10.2/) using the newest universal version of forge for v1.10.2 and the newest version of optifine for v1.10.2 and neither one shows up if i use ML

I have minecraft 1.10.2 and 1.11.2 installed created the folders 1.10.2 and 1.11.2 under mods in C:\Users\*****\AppData\Roaming\.minecraft\

So BlueDrache is not the only one having trouble getting them to work with magic launcher,

they both work with the new mc launcher with forge installed and optifine in the mods folder.

and yes they both seperately work if using their installers

and before you ask I have created a new world for vanilla mc 1.10.2 to try and get them working, i followed the above post #10156 to the letter and still not working so what am i doing wrong? Do i need to have the installer version of forge for mc 1.10.2 installed first or what? I have the lastest installer version of forge installed for 1.11.2 and whenever i use that profile for 1.11.2 and the corresponding mods in ML, i am told that there is no forge installed

I am trying to keep mods for 1.10.2 and 1.11.2 in seperate folders

On my Onedrive there are 4 images I use to explain the installation of my own mods http://sdrv.ms/TPcx5v . In this case , version 1.8 is used for demo . See if this helps

You should update the launcher to look similar to the new Minecraft Launcher (2.0!).

I'd like to see a visual upgrade myself as well, I like the visuals of the new launcher but hate how it navigates

This looks good...

Never worked cant delete

NOPE

i got this and it confused me i kept trying ANNND it never worked. i got this for optifine but now its just not worth it

PS you cant delete this

Somebody mind explaining to me what's going on here? OptiFine doesn't work, but Minecraft launches completely normally otherwise. My only guess is that my Minecraft install and the folder that OptiFine is in are on two different drives (C:\ and E:\), and that's throwing Magic Launcher off.

Edit: Running Magic Launcher as administrator, taking ownership of OptiFine, and moving OptiFine to the same drive that Magic Launcher is on all failed to solve this problem.

Edit: Never mind. I was doing it wrong. The .JAR file is an installer for the mod, not the mod itself. ;>_>

Magic Launcher wont start, it also wont start in admin mode. It was working perfectly fine, I decided to upgrade the ram bought an 8gb(turned out to be a 4gb, got refunded) and now magic launcher no longer runs. it wouldn't run with the new card, and with the old card back in it, it still no longer runs. Both of the cards are properly working in the laptop. Downloaded a new copy, that also won't open. Minecraft runs, just not through the launcher. Should I delete magic launcher entirely and re-download again? Are their program files to delete? Are their some kind of setting files to delete? anything? How do I fix this?

Deleted everything minecraft from program files to roaming files from the computer, redownloaded and installed everything. Magic Launcher still wont work.
