But.. When I try to run the game iether via the FO tab in programs or the "megamOd" tab in programs it gives me an error message and the game wont boot up. "Fallout appears to be running in compatibility mode" prior to the addition of MegaMod it would run ( I tested it with one game which I did not save) I never enabled compatibility mode on FO and am not sure i know how even if i wnated to. a) Is this really the probllem? b) if so how to I run it in normal mode?
