They are only too painfully aware of the issues, we make sure of that. 2 out of 3 causes for the Systemguard failures have already been addressed and, from what I've observed, the 3rd one seems to be almost licked as I'm no longer getting the "Fix" nuisance all the time.
We have been assured that the new 2010 product is totally different in approach and will not even have Systemguards per se, not as they are now anyway and it will also command a much smaller footprint and use fewer resources. I don't know much else about it I'm afraid at the stage of the game, but the impression we Moderators get is that it's a new approach altogether.
It should be available for beta testing in a few weeks for anyone interested. See my sticky
HERE.
Meanwhile, sorry that some of you are having these difficulties but no software is perfect in my experience. The developers only learn from customer experiences and the more you bombard Technical Support Chat the more they will take notice.
The verify subscription bug is usually caused either by system clock errors or browser settings being non-default, 3rd party software interfering or use of Registry Cleaners, which I do not recommend.
