Version of Adobe Acrobat 7 Standard won't activate or upgrade.

I have a copy of Adobe Acrobat 7.0 Standard that I bought on a DVD in 2001 for $350.

I recently got a new computer, and when I needed Acrobat, I loaded it and it worked, but I got a message that I needed to activate it or it would cease to work after 30 days. I followed the instructions at "Activation server unavailable" error in Adobe CS2, Acrobat 7, and Audition 3 but when I brought up the activation wizard and entered my serial number, it said it was invalid. After an hour-long chat session with Adobe, I was told that my number was valid, but that they couldn't help me.

At the best, I'd like to get an upgraded version of Adobe Acrobat; but failing that, I'd just like to know that the version I paid good money for, and which Abode acknowledges has a valid serial number, and which their own website claims can be upgraded, will not be shut down on me after 30 days, for no good reason.
