E_auth_not_ready

Last week i was able to download one book from kobo using reader for pc which I have consistently used. Two books would not download.  I get the message content download failed.  i have tried to resolve this with kobo who told me to download adobe digital editions which i have now done.  When I try to authorize I get the message cod e_auth_not_ready.  Kobe said this is an issue with windows 10 and adobe and to contact adobe for a fix.  Is there one available?
