I'm unable to purchase SlingPlayer for Windows Phone on either the web marketplace, the phone itself, or via Zune for the last 24 hours. I have successfully paid for other apps today.
On the phone I get the error "Marketplace isn't available at the moment. Please check back in a bit. Error code: c101c400"
On zune, I clicked through the Buy Now button on slignbox.com into Zune and after clicking buy, I get "Service error. Please try your purchase again"
On windowsphone.com/marketplace, the error "Can't get app. Something went wrong. Try again later"
Is there an issue with Marketplace going on right now?
