Hello all,

This is the crash report I get after I try and install ModLoader after a fresh force update of Minecraft. Yes, I've deleted the bin folder and still get the same result.

Any help is appreciated.

Do you have any mods in the mods folder??

Namely CUI-1.4.6-ML.zip or maybe an older WorldEditCUI-1.4.5.zip? That's all i can find on "java.lang.NoClassDefFoundError: cui/IMod"

Can't believe I didn't check that before, thanks! Yes I did have WorldEditCUI in the mods folder.

Sweet... total guess on my part from googling "Caused by: java.lang.ClassNotFoundException: cui.IMod" and auto translating some japanese that i found the error in on a .jp site
