ok then smiles if the tables for the arcade arent in the threads database then just try and reinstall the arcade but I would double check and make sure in your threads database you don't have the following tables w3t_arcadesettings, w3t_gamechallenges, w3t_gamenews w3t_games, w3t_gamesessions
if any of them are there then delete THAT table and then try reinstall
