I installed 360 on a Vista machine, and I followed the install directions to the T from the site. My backup to my DVD drive does not work right. On a system reboot, and going immediately into backup, it starts and does like 3 DVD's just fine. Then it errors and says, "There is not enough space on your backup destination. Backup has failed." WHAT THE HECK???? Why does it not just ASK for another DVD???? This same version works just fine, backup works just fine on an XP machine. Backup is configured correctly too. So, what gives? Version 4 had the same stupid issue right before I updated to version 5. Tech support said 5 would fix the issue. I am severely upset. Any way to fix this????
