What are the errors you are recieving? Chances are they are related to the latest update of Simba (a little while ago now), but an awful lot of scripts haven't been updated to be compatible.
Feel free to either post back here, PM me/add me on MSN/Skype.
I've had pretty much every problem and error that simba could possibly throw at me. Feel free to PM me or add invocation.x on skype and I'd be happy to help you out!
