Hmmm... when ye re downloaded the game, were ye sure to delete all the old files? Some old, corrupted files may still be floating around, causing trouble.
Try running the game as administrator. That usually fixes these odd problems. Right click the icon on y'er desktop and select the option that says "Run as Administrator".
Is this a new issue f'er ye or has FH always done this when ye tried to play? Download any mods, item packs, interfaces before this issue revealed itself?
