Minecraft Forums

I've decided to start using a few mods I've heard about, so I downloaded the Forge and three mods to add to the game.

It worked once, but my new world crashed upon loading, and then after that, I kept on having my game crash after the Mojang screen loads. It stays there for 15 seconds and then gives me an error report.

Here's the Report it keeps giving me:



Minecraft has crashed!

--- END ERROR REPORT d711985d ----------

Things I've tried:

The META-INF file (I think that's the name) has been deleted
The forge files have been extracted and then copied and pasted into the Minecraft.jar file using 7-Zip.
I have tried force updating and then re-copying the file
I run 1.4.7, and the forge version I have SHOULD be compatible with that since that's what the website said.
I have tried deleting my Traincraft mod incase it is incompatible with Industrialcraft or Biomes o Plenty.
I have tried deleting the forge alltogether. The game runs fine, but none of the mods work.

If anyone could help me, I'd appreciate it!

I can get the full crash report if it's necessary. I just have to look for it.
