I got an error message saying that file did not exist so I did what I always do when I get the error and found it........then copied it to the aces high directory.
Maybe my computer glitched as a file copy or file deletion was going on.
It was the most recent update which installed just a few minutes before the post........but I hadn't played in a few days.
If nobody else get's it, no big deal.........but if they do.......copying it worked.
Windows XP media center edition updated as far as it can be updated.
