I'm having a problem. I downloaded a few international teams. I added them with FIFA Creation Master 10 in the International league, but when I go and try to select them my game freezes and then crashes. The game still works if I play with unedited teams.

Check that the new teams you have added have a formation set in Creation Master (If they don't the game does crash)
Also check that they have a badge or logo in both the team page and GUI pages in Creation Master.

Thank you. Now the game works.
