Yesterday I changed the name of my main (and only) profile. Today I tried logging on with the new name and I can't get in. I can login using my old username but I am no longer an admin, can't access any of my folders, and cannot change anything in the user profiles without admin user/pass. I can't login as admin because I never turned the option on either. I've tried logging on as admin, administrator and default but I can't get any of them to work. Anything I can do?
