I'm having the exact same problem on Mac OS X Mountain Lion. Deleted techniclauncher folder, and replaced techniclauncher jar. Installed those three mods, then launched what was functionally a Vanilla Minecraft where the menu buttons wouldn't make sound.

What do you plan todo on our server(any major project plans?): Mine for two hours. Get established with IC and EE. I've always wondered how well a small town powered from a central location would work. (Maybe build a Jaffa factory O_o)
