I purchased a license for JRiver MC 20 on a PC. I then tried to uninstall JRiver MC from the PC, and reinstall it on a MAC. JRiver advised that I needed to buy another license. I did so, and tried to register the second license under a different email, to avoid confusion. That worked. I now want to re-install JRiver on the PC. The newest version is JRiver MC 22. I download and try to use the license, and it says this license is not valid for this product. When I go to JRiver web site, and it says I have two licenses, one with 10 re-installs left (presumably the MAC license), one with 5 reinstalls (Presumably the PC license). No matter what I do to try to restore (change emails, etc.) it always sends me the MAC license. But it has deducted another install from the PC license. How do I get the PC license code? Ideally without being charged for any more re-installs.
