OK, that fixed that problem. I wish there was a way to transfer the previous sync setup to the new one, so that everything doesn't have to re-sync.

Try Complete uninstall and delete MMA folders.

I can't start MMA 126; I'm getting the message "The 30 day trial period of this pre-release version of MediaMonkey has expired."
Hit OK, it exits.

I saw that message once earlier, when I started the program this morning, but the program continued and I didn't think about again until it recurred.
