I recently upgraded to Digital Editions 3.0 but can no longer access my ebooks. It keeps asking for a vendor ID authorization. Most of these books were purchased from Kobo. A second problem is my ereader is a Sony PRTS-3 and now it keeps asking for an Adobe ID & pw which I keep entering but it won't accept it. Yikes, so now I cannot read my ebooks on my computer or my ereader. These 2 problems are probably connected but I feel stuck. Help!!
