    Lightroom 5.6 - Application Manager keeps telling me that the serial number is invalid.

      I want to activate Lightroom 5.6. The application manager keeps telling me that my serial number is invalid. This is not the case. I bought it via Amazon.de and it worked a few month ago when I still could install Lightroom without the Creative Cloud. Any solutions? Thanks!
