My Ubuntu is not opening when I use my administration account. My Ubuntu is 12.04 version.

My other user account (which are not password protected) are opening. But I can not access my administrative account through the user account. I can not do anything (update, upgrade, accessing my files,..).

The main problem when ever I give my password it does not open my account like it was opening in past. When I am in my administrative account then I can not shutdown and restart my computer too. It get stocked; I have to forcefully shutdown.

So the problem is not with the password (as it is the correct password) the problem is something else which I can not figure out.

Please help me and guide how to regain my access to my administrative (main) account.

Open your terminal on your "non-protected" user. Then type this:

sudo su
passwd (your user)

After that change your password (or type your old password). After that try to login with your new password. Hope that it solved your problem.
