well like cnopicillin said the mod pack, or unified installer as it is more commonly known must be installed onto version 4.08 unmodded.

Basically install the DVD, then the 4.08 patch, then the UI.

Do not install 4.09 yourself as this is included in the mod pack

Have a browse on this thread where myself and JAMF helped another guy with similar problems to you
