I used to play this game a lot, but hadn't for a while. I recently put it back in and was prompted for an update. When I updated, I lost the two extra race groups, Old vs. New and ?, and I lost my Legends and Speedhunters races and cars. I re-downloaded the Legends and Speedhunters, but all the upgrades and tuning on the cars is gone. I re-entered my online pass code, but I still didn't get those extra races back. Isn't that where those came from, I forgot?

Any suggestions on how to get my game back to where it was?
