Hi, I'm quite new to this whole modding thing, but I really wanted to play with ExtraBiomesXL. I've been trying to install forge for days now but it won't work. Every time I click an option on the main menu it crashes. This is my crash log:[hide]

I've looked around the forum and I saw one person with this same log and someone commented saying that using the latest version of forge would fix it. I am using 4.1.1 so I don't know what to do. I've also tried deleting just the MOJANG files in the META-INF, deleting the whole thing, and just leaving it. All with the same result.

Search.
