Got XP Pro and also get the same error, after pressing OK, I get a second error, this time telling me there is likely something wrong with send-message, after pressing OK again, FS stays minimized on the taskbar, clicking the taskbar icon, FS opens normally and continues to load...eeegad my stick don't work?
so it works in XP, just keep hitting OK to break into the debugger...oh, and btw...FRED don't complain about nothing...error check says all's cool too...ok, it turns out compatibility mode has influence here...without it I can't play at all, with it, my stick don't work...
oh...forgot...got the cd version
