OK.. I may only be half way there! This morning w/o the reader I logged into Sony Store and my account showed the PC and the reader authorized...no problem. ADE was also authorized for the computer. Tonight, I plug in the ereader and ADE doesn't see it (It seems ADE may have some MAC issues which other forum posters are also experiencing). Whats driving me nuts is that the Sony store AGAIN said my PC was authorized on another account and did I want to reauthorize....I declined so as not waste an activation again. The eReader is still authorized in the Sony store account though! Any one have any ideas whats going on?? I'm not reauthorizing anything until I know a clear direction so I don't have to get more activations from Adobe.
