      Hi all,


      I bought and download an upgrade licence (not CC) for lightroom6 On Mac. Previously I had Lr5: The Download was right but when I try to install, it stops after having put the serial number and the reason is :"Impossible validation of this serial number for Adobe Lightroom" Contact assistance"  (this is a translation). But the serial number is correct, I got it from the email message received from Adobe during the download. I tried several times, but with no results. Please help me.

      Thank you in advance
