I lost my slots to when the EA Tech did the gamertag linking for me. I noticed this before I hung up and I knew that the code that came with my game wouldn't work a second time. The Tech fixed that for me as well.
All of this originated when I couldn't find my created teams when I first got on NCAA10. They were created under my web persona. The big test will be in a few minutes when I try to download the team I just finished creating. According to everything I've read, it should work this time
I had my EA persona set to the one that is linked to my Xbox 360 gamertag. Created the new team with a custom logo, so we'll see what happens..................
