Scott,
I've never seen that admin template before, but from what I can see on the page you sent, there's a few things to note:
1) You're using Joomla 1.6.0. We did no testing with that release, and everything was done with Joomla 1.6.3. Between 1.6.0 and 1.6.2 there were over 200 bug-fixes (and about 25 mid-level or higher security fixes). It's possible one of those affected windows installations.
2) Make sure that your permissions are setup correctly for the administrator folder, which is where things are installed. It's possible that the installation of the module and plugins couldn't happen because the directory (com_jfbconnect/packages) is unwriteable.
3) If the admin template (or Joomla itself) is customizing the functionality of Joomla in any way, please try using the standard Joomla Admin template or reverting any custom modifications to the Joomla core you may have made.
Hopefully this helps. I think #1 is the biggest issue above, but it could be anything. We really have seen this report before, so don't know of a specific cause.
Alex
