Make sure that the directory you set it to move the files to actually exists. It's possible that you accidentally mistyped the directory name at some point.

Also, the files may have been in use by some other program when PT tried to move them. PokerTracker moves the files after you close the import window. Next time, close FTP and PokerAce(or any HUD that reads hand histories) before you close the import window in PokerTracker.
