Hello everybody.
Today I've purchased the upgrade from the Extended Polar Version to the new Argo. I'm on a MAC with OS 10.9.5. I had some problems trying to install the license file. I figured out a workaround that I would like to share. The license file was on folder inside my documents folder. From there I was unable to install the file, After clicking the "Install License Key File" button and choosing the new file, it doesn't seem to install it. The window message doesn't change: No License key is currently installed. You need to install a key file and then unlock it. After several tries, I decided to move the license file on the desktop, and from there it worked perfectly...
Good to know
