Can't login, the system through me back to the login window.
I need help. Once I tried to login under admin account but the system through me out after accepting a psw. It happens like it checks the psw shows the blue screen and then return to the login window. Meantime I can succesfully log in under another user account. I tried to change psw and login but it doesn't help. The system is friendly accepting the admin psw for all the possible aims but not the login. Before that happend the system was blaiming me for overfulled hard drive. Now I cleaned it but that doens't help. What shall I do, in order to log in, what is wrong?
I have a time machine copy but recovery of admin user folder didn't help. Many thanks in advance for your assistance!
