I have an 80Gb Zune. I bought around $15 worth of Microsoft points and have purchased four songs, but so far I haven't been able to successfully download any of them - I'm getting the good ol' C00D11CD error. Here's the web help URL...

I'm logged in as an admin, running Vista Premium. My 80GB Zune sync just fine with the the podcasts, music, videos and photos. My only issue is the inability to download the music I've already purchased in the Zune Marketplace. I do not have a Zune Pass, nor have I ever had one.
I'm running v 2.3.1338.0 of the Zune software.
Ideas?
