Invalid Feed

I have a site with multiple podcasts, each with a wordpress install in its own directory.
The main site http://www.playersclubradio.com/feed is valid, however none of the other feeds work.
I am mainly concerned with http://www.playersclubradio.com/midnightatthepcb/feed not working. I have a feeling that it has something to do with how the feed itself is set up and the fact that i’m not trying to syndicate the root directory but there are so many files it seems that go into making up the feed or which are just for show that i’m not sure which php file i am editing even, let alone what code i am changing to make this function. It should be the same set up as the ace network. I might have to email cioffi. I’ve had two IT guys fail on this one so far. Someone please help.
