I am using the 30 day download to evaluate IF I want to purchase a years subscription. I HAVE to say that while I used to use the free version with NO PROBLEMS, this 30 day trial SUCKS. Every few minutes (at best) the screen freezes and the mouse can access the outer screen menus BUT NOT the graphics screen. This happens several times within an hour until I get so frustrated that I close out of the program completely. If this can't be fixed, I am DEFINATELY NOT going to PAY for this aggravation. Does anyone out there know how to stop this from happening?
