Reset Adboe Authorization

Sony eReader under device information shows: This device is authorized for reading and purchasing Abode DRM content. When I connect my eReader to the PC for eReader, a dialog box opens requesting my Adobe ID and password. When I enter this information, the dialog box disappears for a few seconds then reopens again. I have reset my password and it was successful. Sony support said that Adobe.com has to reset my adobe authorization. I have had this Adobe ID for over a year and this problem has only occurred with the last two weeks.
