Have just downloaded v4.5 to my pc (Windows 10) in order to download books from our public libraries; program appears to be installed O K. Ordered book from library, but when ordered and then Download For ereader I get error message - Error! Check Activation. Have been back into progarm Help/Authorisation Information, which confirms 'This computer is Already Authorised'. To check if problem with the system or elswhere, brought up Adobe Digital Editions on another webpage and downloaded one of theit sample ebooks - but got the same error message. Thanks for any help.
