NEED HELP TO RESTORE FROM BACKUP

Thanks for any help in advance. I realize this is not a programmer issue- far from it.

But, I am not getting it when it comes to XP and the User Accounts so I can restore many files from MOZY backup. Windows needed to be reinstalled. Now the MOZY client seems easy enough but files that were backed up in ADMINISTRATOR folder won't RESTORE to my fresh DESKTOP.

MOZY Support tells me I need to select the proper User account but I am not getting it.

The old account name from which the backup were being stored was called ADMINISTRATOR.

When I Reinstalled XP I signed in at startup as FIRSTNAME LASTNAME

User account shows as FIRST NAME LASTNAME, Computer Administrator

I guess I don't understand the assignment of these names for user account

If I just left the signup form blank would it have Defaulted to ADMINISTATOR?

OR

Can I Creat a New User and call it ADMINISTRATOR on order to be able to send RESTORE from backups to the Desktop?

Thanks Very much need many marketing files to continue with the business projects.
