Missing Class File?

[Skribbblie]

I get this error when I try to run Minecraft, with BuildCraft and IC2. It seems I'm missing a class file, it says.

My guess is you don't have the latest version of BuildCraft. Try redownloading the newest version. Hope I helped.

Or you are missing Forge altogether, one or the other.

[Methuselah96]

I don't think so. Lex took out ICustomItemRenderer when it went to 1.2.4. Skribbblie's probably using a 1.2.3 buildcraft or something although I don't know why those mods weren't in the crash log.

[OvermindDL1]

Missing updated forge or an updated mod then, that works.
