Hello out there!
I really spent several hours trying to fix the error myself but I just can't find what's wrong.
This is the situation:
I have two PCs, one with Windows 7 (32 bit), one with Windows 7 (64 bit).
I installed MinecraftForge on the 32 bit PC and it runs perfectly. Then I tried the same (same Forge version) on the other one (64 bit) and I get a black screen.
I tried installing on a fresh minecraft.jar (latest update). No other mods installed whatsoever. No server. I tried different Java versions (7 and 6, in 64 bit and 32 bit) but still black screen.
Please see my error log here:

It seems to be some Java problem but I just don't know what to do to fix this.
BTW when I try to install the very last Forge version (minecraftforge-universal-6.2.1.358) Minecraft stucks at the "Done loading..." screen and I don't even get an error log)
I hope I gave you alle the information needed. Please help!!
