Does anyone have any idea if none of the stuff in this thread works? I have tried everything and moved files around in Steam Apps and nothing. Annoying thing is it comes up in top right of screen when running program! I also stuck Jedro's Taxi's in and that worked straight away (Nice work Jedro)! The ONLY possible thing it could be is the weird named app. Does anyone know the exact name of the file to run as Administrator as I believe i have tried them all, less the files that can't be opened (.vdf, .dat, .pbo, .paa, .cpp etc...) The DataCachePreprocessor that i run as administrator always comes up with "Program might not have installed correctly" no matter if I re-install it or accept it as being installed correctly. It then moves on to the CD key that is on Steam Clipboard. Go into game and it is ticked in expansions. It is in the Top right corner (As is Jedra's Taxi's now). Nothing on main screen, Free Flight, Editor, Time Trials! What the hell am i doing wrong?
