Finally found my first posted message about this mess. When I plugged in the Glo AND the Aura my V2 of ADE did recognize both KOBO readers.
Now I realize that I completely forgot that we must authorize each device we add in ADE. So that is why I was unable to copy my borrowed library books over to the Glo. Sadly ADE did not pop up with a warning message that readers must be authorized. My computer was authorized way back and my Aura was authorized in April 2013 when I bought it.
After doing the set up for Glo with KOBO which is running 3.1 new version I linked my Aura with Kobo desktop and it was updated with 3.1.
Thinking something was wrong with ADE I uninstalled and then downloaded V2 again. Now I went through the computer authorization, NEW account, and then I realized why I had a problem. So I plugged in my AuraHD which was already authorized under previous ADE ID back in April.
New install of ADE V2 would not recognize the Aura, tried the Glo and it wouldn't recognize it either. Did a factory reset of both devices, reset up the AuraHD with Kobo desktop app and packed up the Glo to return to Best Buy.
I can not get any version of ADE to recognize my kobo aura hd device now so am unable to "authorize" the reader.
Now I realize that setting up another NEW Adobe ID account has created some of my probs, older library books don't recognize new ID. But I can download new library books and 'Return' them from ADE no problem.
How do I get ADE to recognize my Kobo Aura HD and let me 'authorize' the reader? I wonder if the newer V3.1.0 from KOBO is creating a problem?
Sorry to be so stupid . . .
