I ran a backup of my data before sending my PC back to the manufacturer for a factory reset. Got it back, reinstalled Norton Security with Backup and tried to restore the backup that I took. It goes through the motions and looks like it's all going to work, but then in a progress bar appears and it seems to stick on 0.0%.
I've left it for hours and it eventually displayed a message to the effect that I should try again later.
Any ideas what is going on?
