Thanks, Benoni! Strike most definitely does not show up as being installed. In fact, if I try to open an old session with a Strike track on it, I get the error that "The following plug-ins were made inactive because they could not be found in the plug-ins folder: Strike (1)"

I've checked all the folders that I thought might contain a "trace" of Strike, and found nothing.

I have not tried any third-party platforms; I guess my unfamiliarity with those programs makes me a bit nervous. But I'll try Ccleaner this weekend if you think it might help.

And there may be some Strike-related files on an external drive (although there really shouldn't be), so I'll try unplugging that and trying again.

Again, much appreciated for the help, Benoni.
