BrokenHeartedGirl.com

So, I woke up today and my forum won't load, and when you click on a blog post, it redirects to the homepage. Obviously, this is not ideal. The guy who usually helps me maintain the site is out of the country and I really need help today. Can anybody help?  I spoke with HostGator.com and this is what they said is the problem:

(11:27:27am)Timothy G.:Further checking it appears to be an issue with the rss feed on line 39 which would be causing the forum posts not to display.  Info on the output is as follows. PHP Warning: readfile(http://www.brokenheartedgirl.com/forum/?action=rss_all&amp;bx_profiler_disable=1) [<a href='function.readfile'>function.readfile</a>]: failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found You may want to check with developer in regard to looking into it to have them loading.

Can anybody help me? And quote me a price please?  Thank you very much.
