ADE 4.5 and Windows 10  When I try to authorise my new computer with a new ID, the Authorise window comes up twice and ADE stops.

RESOLVED:  Uninstalled ADE, deleted Documents /  My Digital Editions folder and sub folders, ran Ccleaner to tidy up Registry, restarted PC, reinstalled ADE, double clicked on the downloaded .acsm file in Downloads, when asked - Authorised the computer with old Adobe ID, epub file was downloaded (probably from the Kobo site) and hey presto, the world is good again.

Off to have some red wine.
