When it arrived, I fired up the installer, used the serial, and everything installed without a hitch. I ran the program and it asks to activate online. "No problem," I think, I used a legit serial from a legit copy, I should be fine. What I didn't consider was that the activation server was taken offline (I'm sure the official reason was "cost savings" but "force people to upgrade" fits in there pretty well in my opinion).
So now I had a perfectly good box of software and a stack of manuals for a product I couldn't use for no technical reason other than the company didn't want me to use it.
