Alright, so it said that it failed to download some libraries, but there's a tutorial on youtube that made the library error go away, lemme try that.

I followed that tutorial, and got the compiler and library, but upon starting up forge, I get the same crash. Any ideas?

Sorry for not replying. No, it doesnt work anyway. I added the forge files to a copy of 1.6.4 and renamed the things and did what I needed to do with the .json file. Minecraft is able to load up, it doesn't have forge's menu, with the Mods button, the "3 Mods loaded" on bottom left, etc. Idk what's wrong. From the crash report, it looks like it doesnt find a file (noClassDefFound)Ok so I tested out something, and it turns out that its just the mod messing it up. But it can't get Animalbikes mod either. Maybe its a forge bug?NEVERMIND! I think I just needed forge to work without mods first. I put the mod after having forge work, and it works now!

outdated mod!
