problems with entering a feed in to the sources page.

hello, I am trying to set up a social networking notofication system that will distribute my posts from my forum, I have your services connected to my ping.fm account and it is all ready to go, one problem though, when I enter my original RSS feed, it comes up with an error message, I have run it through a feed validator and im not getting anything wrong back, I tried to burn the feed with feedburner to see if that would correct the issue, but im still getting the error message. Is there an issue with notifications for the time being? or have I stumbled across an anomaly? here is the original feed and the burned feed for you to check up on if this is something strange:
