Everything worked fine until today. Only differences are that last night I installed XP SP2 and updated my Nero. Then this morning I updated my dvdshrink to the latest vesion. Now (even if I use an older version of shrink which was fine yesterday), when I try to reauthor, as soon as I hit backup, the drive tray opens. Is it Nero causing this? I unchecked the enable nero burns box but still no joy. I did a search and saw that a few other people had this issue, but nobody seemed to be able to solve it. HELP!
