Tivo Desktop Error: Unable to Begin Tivo Desktop The Filename is Too Long

Hi folks, I've had Tivo Desktop for years, but I'm having a new error message I've never had before and I can't figure out how to get rid of it and to get Tivo Desktop to load. I don't think Tivo support will be available until tomorrow, so I thought I'd ask if anyone here has encountered it or has suggestions about what to do.

I'm using Tivo Desktop 2.8.2, an HP computer and Windows 10, if that makes any difference.

I suspect the problem is a file I had created using Video ReDo earlier...
