Have you tried "Admin"? Your stuck with guessing here unless you can get the sender to tell you the account name. Admin is built in default account name so a lot of developers just assign a password to admin and use it as their full access account/password.
If this solution was from an older version than 7, I'd suggest entering the password in both the account name and password boxes...
Yeah, tried that & also the password in both boxes. Still locked out. Thanks for verifying that I've done all I can. I have a call into the person who created the CD so hopefully they will get back to me with the info.
