Okay so, a few years ago I bought Bioshock 2, I got maybe half-way through, then I got a Windows LIVE account, all my saves were gone, I found the save folder and they were there, so I tried signing out of my LIVE account, saves still wouldn't load, so I just forget about it, found other people had the same problem, I have never finished Bioshock 2 because of that.
NOW, yesterday when Bioshock 2 was on sale I decided to try and fix my saves by changing my LIVE gamertag, it still didn't work, I changed my tag two times, however I didn't noticed that it was using my trophy points to PAY to change my name, it didn't fix my Bioshock 2 saves so I just quit.
TODAY, I booted up Arkham City for some fun flying around and beating up thugs and such. Saves are gone, I try changing my gamer tag back, turns out I ran out of trophy points and now they want me to pay $5 to change my name. I found the save folder for Arkham City, everything is deleted.
