The index.php is the forum file path that I'm normally seeing on vbulletins, that takes you right to the forums home page. Now in your case the forums file path for your forum home page is located at the forum.php forum file path. We have never seen that before, so I'm going to have to do some coding I think. I will check with my partner on Tuesday about this because that is out of my scope of programming.
Any ideas why your forum home page is like that? We have no problem recognizing and following your topic file path, http://www.lincolnvscadillac.com/forumdisplay.php?f=1
This path takes us to your forums threads page.

Compared to our grabbed forums following the Forum File Path and the Topics File Path: we pull back 64 unique forums. I think the structure of your forum is throwing us off. As I said before on Tuesday I will ask Al (my business partner) about this or maybe if you can set up a mirror site with just a list of forums using index.php and forumdisplay.php we can just crawl that on your backend. That might be a real pain for you so I'm thinking I will just ask Al about this on Tuesday.
Joey, I'm really sorry about all this trouble. I have never seen this happen before but on a good note we are finding one more way message boards are structured. The real funny thing is we can grab the forums just fine, but can't crawl the threads. STRANGE. Let me know your thoughts.
