I downloaded ADE V 2.0 again. Authorized my computer, downloaded a book from the library and a book I own from KOBO. No problems, both books are in ADE.
Shut down ADE, then I plugged in my AuraHD, check to make sure it shows up under Computer as Drive E: and the Kobo is recognized as drive E.
Fired up ADE and waited, waited, waited and ADE will not recognize my AuraHD.
Sure wish there was someone at Adobe that I could talk to . . .
