Update failes with "Bad Parameter"

Hi.

After i updated to 3.8.65951.447 update check don’t work any more.
After i click it, it directly popups an small error box with the message “Felaktig Parameter”
wich would Bad/wrong/faulty Parameter in english.

I havent tried re-installing it, since update is the only thing that’s broken…
I’m running XP SP3

A reintall fixed this problem.
Just got the time to do it
