AuraHd appears in Explorer under "Computer" there is the usual Drive C and then "KOBOeReader (E:).
Back to the beginning: Aura was already recognized by ADE since April and working seamlessly.
Nov 30 Set up and plugged in the new Glo and (my Aura) and both showed up in ADE but I was unable to transfer library books to the Glo. The warning said the books were licenced to anther User and I thought I was restricted to only one Reader. I forgot I had to Authorize the Glo.
After that things went downhill rapidly because I de-authorized my computer and Kobo, did a factory reset on both eReaders and set them up again and syncing with KOBO. I uninstalled ADE and started over with a new authorization for my computer but now ADE won't recognize either eReader so I can't even authorize the Readers.
Thank you for taking so much of your time to help me.
