Somewhere, hidden where noone will hopefully notice it, is probably a configuration file that tells the game where its pieces are. It may be a config file in the directory where the game is installed, it may be buried in the registry, or it may be linked in the starting icon. Or someplace else entirely
Search through those areas looking for C:, and you might have enough luck to clean it up. Failing that, a reinstall (with game backups, of course) will likely fix the problem.
I had a world of trouble when I installed a second hard drive on my daughter's PC. Almost every game blew up because the CD was now E: instead of D:. Not fun... especially since no one else here can figure that out, and she wants to be attended to immediately upon problem discovery...
Good luck on the new machine! That's always a fun time in life [img]smile.gif[/img]
