I really thought someone here would know. I figured I was not alone. I guess I have (had) a unique problem with MC. Not one comment... usually lots of folks comment when I ask a question. Usually very quickly, and usually with a solution that works. Not this time.
The choice? Give up on MC, or give up on the PC and rebuild it. A hard choice but we rely on our media, and MC had been down for over a day!!
I had to format the machine and start over. That fixed it (of course), but a way too radical a thing to do to stay with the latest version of MC. I lost all my other programs and settings.
I have two machines, one just for music in the man cave, it took 28 no problem... but the main machine, no matter what I did or how I did it, the install of 28 would stop responding at "Upgrading Version".
The main machine does video, including HDR, which was really tough to set up. I wonder if that broke it?
