Why is force update grayed out?

Because it's not implented yet.

Quote from cheese200

Audio mod not included right?

No mods are included. This is just a launcher. The mods you have to get yourself.

Quote from Brut_Man

Got mine working again :biggrin.gif:
Is there a way to share mod configurations, I would like to play BTW and Buildcraft but I can imagine it being a total pain in the ass to get to work.

the ideal thing would be something a community kept log of ideal load orders. For those familiar with modding oblivion, fallout etc I am basically talking about BOSS( better oblivion sorting sytem) google it. But in an ideal world it could work well

EDIT: surely just get better than buildcraft? the official combination

Someone really help me fix this error, i really want to play, and i can't if no one will help! :sad.gif:

How can I use the newest Magic Launcher with ModLoader, Optifine, AND Better Than Wolves with no conflict or errors? Or is it just not compatible?

I must say I do enjoy this launcher, as it has allowed me to actually install my first modification to the game of Minecraft, but to expand to the more 'entertaining' of mods, other than OptiFine as I have now, I'm in need of Modloader. So, I downloaded it and placed it in my 'Setup' with nothing else and attempted to run it, but I only received a message like this:
What do you make of it?

Okay, apparently I forgot to delete meta-inf *FACEPALM* But there's still an error going around.

You have Java 1.5 and some of the mods need Java 1.6.

Your minecraft.jar can not be opened or is broken.

Could you add the ability to have certain worlds only show if you are using the right profile?
For example if you had an IC2 world and you wanted to keep it safe you could make it only show if you are using an IC2 profile or one you set it to show it on.

Nice idea, added to TODO list.

Seriously, everybody else is getting help, but I'm not! I need help on getting rid of this error!

The error is very general and may be caused by many things.
Start with a clean minecraft.jar, test that it works and start adding the mods one by one until Minecraft refuses to start. Then post the log file again.

Here's the log again, it happened when I placed the .class folders from modloader into minecraft.jar

Hey, sp614x! You should make it so that this launcher will work on offline accounts. I tried to install it for my little brothers, but it wouldn't work because they don't have their own account, and I won't let them have my password.

When are you going to implement the auto update/ force update feature?
