However, that NFS has since been removed and is no longer used, but ever since disconnecting it, FileBot continues to try connecting to it (or something) every time I click the file explorer button to select files. It's become so annoying that I'm now reduced to having to drag and drop everything onto FB, because this behaviour has become so annoying.
This is what I see each time ...

I've uninstalled FB, run CCleaner's registry repairer, rebooted, then reinstalled FB, and the behaviour just persists.
I've never seen behaviour like this before, so if anyone can help me sort it out, I'd be very appreciative.
