ive been using xbox 360 backup creator fine on windows xp and vista and burned backups and theyve always worked fine w/ no problems. i formatted my computer and installed windows 7, and i got xbox 360 backup creator w/ img burn working fine on it and it burns the backups fine, but when i try to play it in my 360, it just shows the xbox 360 screen w/ the logo. like it thinks it's a movie dvd rather than a game? any ideas? i had never had problems before windows 7

edit: looks like the title got cut off after the post and i cant update it
