I've used SecretRooms Mod on ModLoader and it worked perfectly. I, however, like FML SOOOOOO much more but after i install the CLASS files, the Mojang screen comes up and then the screen goes black. I installed FML first on a clean .jar and there is no META.inf. It seems that no matter what i do i can't shake the problem. Here are the last 3 FML .logs, i cant remember which one it crashed on but it was one of these.. ForgeModLoader-client-0.log ForgeModLoader-client-1.log ForgeModLoader-client-2.log
