Is it possible for you to restore the original ibproarcade you had installed? If so, uninstall vBArcade first...
Once ibproarcade is restored, install a fresh vbarcade on top of it (be sure to set vBArcade to use only best score) and use its import function to get all your games (be sure to check to include Scores with this process).
When all the games and scores are in, you can uninstall ibproarcade, including the gamedata folder - all the media assets will have been moved to the central vbarcade folder.
Let me know if I can be of further assistance
