Norton AV '09 wont open

Recently got Norton AV '09 and all was working however now when I log-on Windows Norton fails to load and if I hit the Norton link on my desktop it wont open.  However, if I log-out and log back in as my wifer (two users on XP) it will open.  However I dont believe it is particular to my log-in because if I log in first as her it wont open either and only opens if I then I log out of her side and log back in as myself.

 

I have re-installed Norton 5 times (using uninstaller tool), run scans (once I finally get it open), and run Malwarebites (did find to issues, whic were resolved) all to no evail...Still wont start or open when I log in.

 

Any suggestions????
