ok, so i'm trying to log into my user profile, my non-root profile, and this is the message i get immediatly:

'Your session only lasted less than 10 seconds. If you have not logged out yourself, this could mean that there is some installation problem or that you may be out of diskspace(of which i'm not out of diskspace). Try logging in with one of the failsafe sessions to see if you can fix this problem(that doesn't work either).'

so, what do i do? i'm think of creating another user, and copying all my files and such there, and deleteing the old one. i hope this will clear things up for me. but any suggestions on how i can REALY fix, or atleast find out the problem?

alright, never mind. for somereason this worked, and i have no idea why. i created a new user, and now my old one works. thnx for the help :-D

turns out i was out of space :-D
