First thing I noticed is that your secondary pages link to images using a URL like:
http://www.bowlingventures.com/BVc_13/wp-content/themes/bowlingventures/images/m2u.jpg
whereas your home page uses:
http://www.bowlingventures.com/wp-content/themes/bowlingventures/images/m2u.jpg
Not sure this helps, but perhaps this will help someone else figure out what is going on.
Are you sure that the home page is being loaded from WordPress?
