Help! I've killed my version of Code References.

I thought I'd tinker a bit, so I copied the folder where the FoxRef.App is stored, and then changed the reference to it in Options. When I tried it, nothing happens ... screen flickers some, then nothing.

So I put the reference back to the original folder. I had changed nothing there. I get the same result now ... screen flickers, then nothing.

Any ideas?

Thanks in advance,
