No, you don't have a corrupt profile but this article DETAILS WHAT TO DO and WHERE those files can be found.
As to System Restore, Norton does break that.
I accidentally deleted on of my key user accounts and thought it would be easy to get it back using System Restore in Windows XP [location: Start - All Programs - Accessories - System Tools. I'm running XP Pro V5.1 SP3 on an HP NC6000 laptop. Anyway, I kept getting the error "Your computer cannot be restored..." which caused me to begin to panic. Nothing I tried seemed to work. As a last attempt, I turned off my anti-virus and firewall (Norton 360 V126.96.36.199) and booted the PC into Safe Mode by pressing F8 during the boot. I ran System Restore and it worked perfectly. The user account came back and everything seems OK. I just wanted to post this in case anyone else ever has a similar problem. I'm not sure whether it was turning off Norton or booting into Safe Mode that fixed it, but I'm sure glad one of them did!
