Another way to make database repairs like this is to go into your SQL server console, if you have one. A common one for MySQL is phpMyAdmin. As part of that, there is an ability to browse a database and perform hand edits. There are different ways to get there, but many site will have it under the "CPanel" web site control console.

The first time I installed Profiles, I knew I needed the user with ID = 1 to be an Admin level user, and I was ready for that. What I didn't know was, they'd changed the password on that account! Everything was locked out! I went into phpMyAdmin and rearranged the user IDs to change the user ID on my account to 1. Problem solved!
