Hello, I was just installing ExtrabiomesXL for the first time. When I ran my game, it crashed. I am using Magic Launcher (works great, by the way) and Forge Modloader and about 30 other mods including BuildCraft, IndistrialCraft2, PowerCraft, NEI, and RedPower. When I disable ExtrabiomesXL, it runs normally.
