Cheaper yet is a Nokia n770 on ebay from someone who had to have the n800. I've had the n770 for over a year and it works pretty good. A little flakey at times, but ok.

They called it the 2.70 patch. That was for Adobe Acrobat Standard Edition.

I went through this same problem. Don't accept the reinstall. Call support and they will give you a special version that activates differently. I had to go through the reactivation three times before they would give it to me, but they finally did.
