I posted this a week ago and got no response. I'm going to try once more before I get my money back.
I have a feeling I have a similar issue to what I see in this old thread, http://www.gravityhelp.com/forums/topic/no-confirmation-being-displayed-and-no-mail-notification-or-entry-being-sent#post-3454.
Problem is, I don't have the slightest clue where to start to get it fixed. Any ideas out there? I know that we had to do something fancy with IIS and our serve a while ago to something related to permalinks, I just don't know exactly what that all entails.
