RSS Feed URL doesn’t work?

I have a brand new site setup for a friend over at http://www.biggreengenie.com and almost everything is working great so far. However, for some reason, the RSS feed doesn’t work. I’m using http://www.biggreengenie.com/feed just like I do for my other wordpress site, damnshortstories, but it’s not working on the new one with a fresh install on 2.6.3. On DSS, I’m using 2.6.2 and it’s fine.

Any help would be appreciated, thanks!
