I do have the installer on my hard drive for the 4.8.1 version. I purchased it on 18 Oct. 2005. So it was five months ago instead of four. But how can I tell if this version is the basic version or the purchased one? I know that I was under the impression that I bought the lifetime subscription. I even told friends about the price of the lifetime version and how much of a good deal it was. But if I ultimately have to repurchase the subscription, can you tell me if this is a lifetime subscription? And after the 6 months of free upgrades, what happens if you want to update after that? Will I have to pay another $20? Thanks in advance for all your help.
