Minecraft Forums

Basically, I wanted to play crazycraft 3.0 but it wasnt working so i go looking everywhere and i figured that i needed to delete everything from my minecraft folder, replace it with crazycraft 3.0 and then install forge on it and run it. It worked fine on 1.7.10 but the version i wanted to use was 1.6.4. So i went and did the same thing but with minecraft 1.6.4 instead. When i was downloading the forge 1.6.4 it said grabbed 2 libraries requaired. Then when i tried to launch crazycraft using forge 1.6.4 this crash report popped up. Pkease help me!!

Here is my crash report:
