Open Salon: Your Feed Could Not be Retrieved

I’ve had no luck connecting with Open Salon. Everything I try to enter the feed address I get some variation of this message:

We’re sorry, but your feed could not be retrieved. Reason: Could not retrieve feed from ‘www.visioncarriers.com/wordpress/wp-rss2.php’

I’ve also tried feed://www.visioncarriers.com/wordpress/feed/ with the same result.

I’ve written support several times and never received a reply. I’m disappointed because it looks like it would be great platform to promote my client’s blog. Has anyone had any success connecting with Open Salon?
