Displaying font name instead of text.

I just installed dynamic rendering and spent some time getting it work for my website and I hit a problem. I was trying to use it to replace the h2 headers using a zen subtheme. The selector I used was #page h2 and it replacing the h2 header although it is now printing out the name of the font I was using (in the correct font) instead of the text that should be in the header. I am guessing I made some simple mistake along the way, any help would be much appreciated. Also if I am posting this in the wrong place can someone please point me in the right direction?
