Darin,
The problem you're having now is that some extension (it looks like your template) is trying to compress and minify all of the Javascript files on the page. Unfortunately, it's creating a bad file. The file that's being included on your page is:
http://www.saviorofmankind.com/index.php?jat3action=gzip&jat3type=js&jat3file=t3-assets%2Fjs_bff90.js
Since that file doesn't work, and it's removing our Javascript file (jfbconnect.js) from being included on the page, the the login isn't working.
You'll need to fix, or disable, the Javascript minimization stuff and JFBConnect should start working properly. If not, let us know.
In the future, if you're ever having issues, let us know. Not sure if this was also the cause of your 4.1.0 issues, but the best way for us to fix things (when they are in JFBConnect) is to let us know about them
Best of luck,
Alex
