Google Bot doesnt navigate through site

[Residue]

I submitted my site to google ~4 months ago and everytime the Google Spider visits my site, it gets stuck on index.php and doesnt browse the site.

Im using vBadvanced CMPS ( www.jdmcentral.net/index.php ). I thought maybe this was a part of the problem, so I submitted another url to google, direct to the forum ( forums.jdmcentral.net/index.php ), unfortuantely this also has not fixed the problem.

Because of this, Google is not viewing the contents of my page, therefore google searches pull up no information for my site. I am not having any problems with submissin to yahoo, msn, etc etc.

Any help is greatly appreciated.
