Lightroom 5 Serial number rejected on new Mac Book
I bought a new Mac Book Pro and am trying to copy my Lightroom Catalog to the new machine. Actually everything worked fine, but Lightroom won't accept my Serial Number. I know it's "old software" but what's wrong?!? Do I have to use the Adobe Creative Cloud Desktop App? Or not? Lightroom opens and asks for the Serial Number but won't accept it. I can use the software in 30 day trial mode....
