Back-up of Back-Up

[DarkBuu]

I have tried to make a backup of a backup of Dead or Alive 2 limited edition using diskjuggler v3 and everytime i try to make an image file of the game i get an error that says "illegal mode for this track , invalid packet size" What am I doing wrong because I have made backups of other backups and it usually works fine. Thanx for any help.
