I have just bought a new PC and installed Windows 10 Pro Version 10.0.1773. Subsequently I downloaded ADE Version 4.5.10. When I opened ADE every book I have ever downloaded (despite having deleted read books from ADE previously) appeared in the library! Furthermore, if I click on say 'File' or 'Library' or a book icon the programme says 'not responding.' ADE also freezes and to exit the programme I have to do so via my Task Manager.
Any helpful advice would be gratefully received.
Followed you advice 'start with run as admin' - still doesn't work! Any more suggestions?
anything worked? same issue here.
