Since new Acrobat Pro DC Update no cloud access from Windows PC anymore

To whom it may concern,

Since today the new Update of Adobe Acrobat Pro Dc installed I have no more access from my Windows Computer from within Adobe Acrobat Pro DC. The cloud folder structure cannot be accessed anymore. I checked whether I am logged in. This was fine. I accessed my cloud online and can still access it from my Ipad. Anybody having an idea why this is not working anymore since the new Adobe Acrobat Pro DC update. A complete reinstallation did not solve the issue. Help very much appreciated!!!
