Minecraft Forums

So since 1.3.2 came out and I updated, whenever I try to start up Minecraft it gives me a "Minecraft has Crashed!" screen directly after the Mojang Logo Screen. I'm using an un-modded, fresh version of 1.3.2, and I've tried to use Force Update and I've tried removing my .minecraft/bin folder and updating again. These methods have yet to help me at all, and each time the same error occurs.

Here's what's said in the Crash Report text file it gave me each time I tried to log-on.

Any help on this would be much appreiciated.

EDIT: I just tried things out with my older .jar files (As far back as 1.2.5) and the same error keeps coming up. So I think that the problem being based in the new update is highly unlikely.

I've encountered the same error.

Report if it helps...

try updating your java, if not work then delete everything in .minecraft folder but the launcher and run force update

I have this problem as well. And not just with this, but with my MCP 1.3.1 test client ever since I updated. Perhaps java is corrupted?

Quote from diamond_rake

try updating your java, if not work then delete everything in .minecraft folder but the launcher and run force update

It seems that deleting/removing everything in .minecraft did indeed help. I'm not sure exactly what the problem was however since the only things I made sure to keep was my Saves, Screenshots, TexturePacks, and outdated .jar files.

Thanks for the suggestion, Rake ^^

I tried deleting all the stuff in my fresh-brand-new .minecraft, but, it keeps on crashing.

I have the same problem except it was AFTER I finished installing the herobrine mod. Also i have version 1.4.6. Here is the error report:

I'm having the same error, over forge. I'm using 1.5.2, and ever since i downloaded Dzvark's Mo'creatures mod, as well as the custom spawners. First, the forever black screen. I force updated, deleted Mo'Creatures, Custom spawners, and Biomes-a-plenty. Really mad(because this was only my first day using forge), I redid all of the forge things, deleted META.INF, ect., then, i added several mods back into the folder. First was BiblioCraft-Mod-1.5.2.zip, Then ComputerCraft1.53.zip, Then DragonAPI(11)[this is reqired by the next mod i belive.] LotsOMobs.zip And finnally RotaryCraft-BetaV031b.zip. Would love some help, going to try removing a mod or 2 and then praying to god.
REALLY NEED SOME SUPPORT BYEEEE

{ok. so i deleted all of the files and nothing worked. Just going to reset and go back to boring...old...minecraft...}

try deleting the bin folder then start the launcher

it doesnt work for me because it says other program is using it

but it may work to you guys
