I never ran into that problem with the Mogul, so I can't help much on a resolution. My only suggestion would be to make sure you are running the right version. Go to
http://discussion.wmexperts.com/forumdisplay.php?f=172 and look for a thread by codyppc. I would link to the exact thread, but I don't want to violate the terms of ppcgeeks regarding the threaded sms app.
