Can anyone help with a problem with dd's Sims2 game? She has Sims2 Deluxe, Family Fun Stuff and Sims2 Seasons. She's now acquired Sims2 Open for Business but her computer (Windows Vista) keeps showing a message 'You are running the wrong version of the Sims2. Please run the Sims2 Seasons instead.' and it won't let her play SimsOFB. Does this happen with all expansion packs and will she need to take off 'Seasons' to play OFB? TIA!
