Walter,
Windows Live is one of the more picky networks to get going. Here's what we'd recommend:
* In the JFBConnect -> Configuration area, set "Debugging Mode" to "On". That may show more details about what isn't working.
* Double check you've gone over the
Windows Live setup guide
. Specifically, point #5.
* In the same area, set the "Disable SSL Validation" to "Yes" to disable a security check (this shouldn't be enabled normally, but enough hosts have issues that it could help).
* If you still have issues, try logging in from different variations of your site, like:
www.yoursite.com/
www.yoursite.com/
yoursite.com/
www.yoursite.com/
I hope that helps, but let us know what progress you make and we'll go from there.
Thanks,
Alex
