HELP ME PLEASE...log in profile is invalid.

I have a sony vaio with windows vista. I bought the lap top less than a year ago, brand new.

Lately I haven't be able to log on to my profile (admin). I have a guest profile and I can log in that one with no problem. Today decided to go in under safe mode and that was succesful. I then took off the password and restarted. When i tried to log on again, it gave the same error message.  I then went in under the guest profile and downloaded hijackthis.

Problem now is that I don't know what the log means and i'm not sure where to go from here. Please please help me.
