another question (crash with monkey matrix moves 1.2b)

[dr.dr.]

Ok, this probably has nothing to do with coding either, but i intstalled the 1.2b beta version of monkey matrix moves for ut 2k3, when i installed it, none of the unreal apps. ie. unreal editor, ut2k3 wont work. it said that, well this is it:

Can't find 'ini:Engine.Engine.GameEngine' in configuration file

History: UObject::SafeLoadError <- UObject::StaticLoadClass <- InitEngine

thats what happens when i load ut2k3. this happens when i try unreal editor:

Can't find edit package 'Core'

History: UEditorEngine::Init <- UUnrealEdEngine::Init <- InitEngine

can someone please help me? it really sucks when both are off because it is almost the only good game i have.
