I have MC21.0.90 but MC22 reject license key that is higher version of 21.0.83 as forum mentioned.It should accept old key for MC22. Am I wrong ?
You have a license for MC15. I can't find anything newer. You can use it to upgrade. https://wiki.jriver.com/index.php/Upgrade
Here is my MC21 screen shot.
I believe I have MC22-not sure. A while back I received email asking to upgrade-after an attempt I have lost allaccess. Not super savvy with tech stuff, but a long time audiophile-I just want my MC back. Need Help...
