Pinnacle Game Profiler works now (with tutorial videos)!

Okay, I figured out what the problem was, and apparently it has to do with how your PS3 controller is configured in MiJ.  Thus, non-PS3 controller users shouldn't have any problems as long as they run PGP as an administrator.

ja_4251 on the PGP forums posted a great tutorial on how to get MiJ properly configured (the only error is you need to have L1 & R1 set as buttons 5 & 6, and L2 & R2 set as buttons 7 & 8.  Then disable the z-axis): http://pinnaclegameprofiler.com/wiki/index.php?title=Motioninjoy_and_PS3_Controller
