Admin Acct IS NOT in User Acct's

Please help. My Dell Inspiron went wacky. I lost my ADMIN user info (AND
all data under that name). Resulting in my not being able to load software
OR EVEN import my Outlook 2007 pst back up files, and manage my NAV 360
restore backups...
My question is, HOW CAN I GET MY ADMIN ACCT BACK? It shows up under my
doc's, but when I try to access I get "file is denied accesses"

Is my only option to format and re-install XP Pro? If so, do I use the
Re-install CD or the original CD?

PLEASE Help,

B Blake
