Forgot admin username and password

Hello everyone,

This is an unusal request and I feel little irresponsible but I have no idea what my admin username and password is. I created a small photo gallery a couple years ago just for my personal use. Well I decided today I wanted to edit some photos and realized I dont remember my admin username and password are. I tried the admin recovery method and posted the login.txt in the gallery2 folder. This allowed me to change the password, only problem is I dont know what the admin account is. I tried admin and administrator and that did not work. Is there a way to see what my username is so I can change the password?

Thanks for your help.
Charles
