Re: Theme won’t update
I took BP Template Pack for a test spin a month or so ago, once, out of curiosity 
Some notes:
1. Need to make sure that you have ported the HTML div structure of original theme to template pack. Watch out for div iD’s and classes of content area and sidebar. There’s an error page on the link you provided. If I remember correctly from yesterday, it seems like you have not renamed the div surrounding your content and sidebar, otherwise the page layout would’ve looked like your regular pages even if the BP components were somewhat lacking in style
2. If you’ve disabled the BP Template Pack CSS in options, copy the styles available in https://svn.wp-plugins.org/bp-template-pack/tags/1.0.1/bp.css to your active theme’s style.css then adjust to taste
