I tried that as well, actually.
Tudoreleuu did force update! It misses. (didn't work :c)
Maybe. In the MagicLauncher setup menu, Forge does throw me 2 errors, while optifine throws me one, so that might be a problem.
Reinstall it until it works. Otherwise, install it from elsewhere, or stop playing Forge.
I installed a non-nightly build, still crashes. And you don't "play forge", it's necesary.
Also,
I don't fucking use MCPatcher! Plus, it's incompattible with Redpower.
I use optifine, just look at the picture ogm!
