The suggestions posted did not work. The steps were really for working on a
PC and did not clearly describe the steps for a MAC. (By the way, the xml
file doesn't have a tag deviceID.)
I stumbled across another posting by searching on User not activated - MAC -
library book help <http://forums.adobe.com/message/3362815#3362815>which had
all of the proper directions for a MAC.
I am disappointed with Adobe for not fixing this bug. The thread mentioned
above had many postings which means its a common problem.
Thank you Rizwan. You're the best! This worked for my PC/Nook WiFi combo.
