Can't fix an user account in Mavericks (frozen)

My regular user account on my Macbook Pro running Mavericks froze and I had to shut down the computer with the power button, but every time I restart the computer and login my user account it freezes and doesn't respond to any command. It stays with the spinning beachball and does not respond to any menu (not even force quit). I have already tried safe boot, restart in recovery mode, checked the hard disk and permissions with disk utility and still have the same problem: can't use any programme on my user account. When logging with other user account the computer seems to work fine. Any thoughts on how to fix it? I need it fixed asap!!
