Problem with the GUI

Vista SP2, 32 bit
CIS V5 (no AV)

I have V5 installed since the last 4 or 5 weeks and never had a problem.
Today I noticed that when I open the GUI and go to Firewall, wherever i click makes the GUI non responsive and the icon disappears from the task bar.
I open Process Explorer and cfp.exe is not there any longer. cmdagent is still there.
This only happens with the Firewall part. If I go to Defense+ or More everything is fine.
Any ideas?



Problem seams to have gone.
