Hi. This really isn't a public issue, so am only posting in the forum because I don't know how to reach JRiver folks otherwise. Sorry if this is not the right place.
I have had terrible computer luck in the last six months. After installing MC 21, I had issues with my desktop machine after upgrading to Windows 10, so did a clean reinstall, which used up another install for MC. I then began to have random Windows crash issues, with daily BSOD's and never the same explanation in the logs twice. As a result, I reinstalled Windows and MC at least a couple more times. I finally got SMART drive issues that resulted in my having to replace the HDD and reinstall Windows yet again - and yet another MC installation. Then, it turned out that my choice of a substitute drive was a bad one (I failed to realize that it was a green NAS drive, which was both slow and unwilling to play nicely with my Intel Rapid Storage Technology setup.) I finally broke down and bought a new hard drive, which arrived this morning and now I need to install MC yet again.
In the same time period, I upgraded my laptop. Between the original and the new laptops, that was two more MC installations.
Where I am going with this is that I am about to install MC for the tenth time since I purchased. Your support sticky says to contact you if I run out. As of later today, I will have used my last installation and I just wanted to be on record in case I need to install again after this for whatever reason. Thanks for your consideration.
