David,
I just sent you an email with the JFBConnect zip files for the 4.0.3 version re-zipped, which should work on your Windows system. We did some testing, but it certainly wasn't exhaustive. Hopefully, you won't have any installation issues, or configuration issues thereafter, but if you do, just let us know.
So far, we are planning to use the zip format for all future releases, but will be testing the 4.1 release fully before we commit to that decision.
Good luck, and thanks for your patience,
Alex
