I had an issue enter into my system somehow. I suspect it had something to do with a Windows update, which was recent. Nothing else had changed or been installed otherwise.
Anyway, something was wonky and I could tell I wasn't going to get it sorted.
So, I took the plunge and restored the entire hard disk environment from my most recent Acronis backup.
A few hours later (after everything restored through), I was back. Everything worked just as before. Everything is fine.
I'm very appreciative of Acronis and having the backup strategy.
