Formated my C: drive and reinstalled windows XP and now everything works fine <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />.
Pfew, can't see an other installer for days (probably even weeks) had to do a whole bunch of windows/linux reinstalls the last 2 days... But anyway it works now, everyone is happy, so now party on <img src="/ubbthreads/images/graemlins/party.gif" alt="" />
