Maybe a stupid question, but have you tried it with a clean minecraft.jar and the latest ModLoader and ModLoaderMP?
I don't see why it shouldn't work on a clean jar with only ModLoader and ModLoaderMP.
yup. before posting that error message i redownloaded my MC by forcing update, and got V3 modloaderMP from here and same with all the SDK mods, then because I was having trouble before V3 I tried with modloader normal and modloaderMP put together boom, dead. I just have no idea what to do with it. >_>
