Live Update automatically disabled

Hi,

 

I am using Antivirus Gaming Edition 2009 under Windows XP on three different PCs (1 desktop and 2 notebooks). 

 

On all PCs I have the problem, that the Live Update automatically disables itself after some days without any user intervention. After enabling it again it works fine, but then after some days it is disabled again and some days later Windows will complain about that. After being disabled it stays in this state permanently. On one PC for over 150 days ...

 

 

Any ideas?

 

Thanks,

Holger
