Mac OS X 10.7.4 & EOS Utility 2.10.4 can't find 5D mark II

Excuse the new thread .. couldn't find one that addresses this so ...

I have a 5D mark II and a Macbook Pro that used to communicate with each other via EOS Utility without problems. However, I recently installed OS X 10.7.4 and can no longer find the camera with EOS Utility. I searched around and found out that there's an update for EOS Utility that supposedly fixes this issue so I downloaded the update from Canon's site, ran the update, and now have EOS Utility 2.10.4 running. Unfortunately, EOS Utility still isn't seeing my 5D.

Any ideas?
