I think they've misunderstood the problem. It's not so much that Awasu can't handle it as it's not being given the feed properly. Either they're publishing something very odd or the feed is getting mangled somewhere down the line e.g. at your ISP or on your computer. Regardless, if Awasu is being given a bodgy feed, there's not much it's going to be able to do with it.
"Can't read the URL" means that Awasu isn't getting anything at all (this is a Windows error, not an Awasu one). Together with the fact that it's OK in Firefox suggests that you've got a problem with your IE somewhere.
