Great product. Tried for the 30 day trial period and bought a 2 year subscription. However, twice so far now, when the program tries to update, it says I'm "so many days" over the free trial period and I'll have to purchase a full subscription. Most times it updates fine. When the above happens, I just click on the Upgrade/Purchase full version ...don't have to enter any username/password things and it downloads some stuff and all is well. Just wondering why this happens time to time when I have purchased a 2 year subscription?
