Strange indeed. The first thing I would have suggested would be to do an IPTV Reset, but it sounds like you already went that route. I know they are doing some upgrading of the Stalker Middleware. I don't know if that could figure into the issue.
It was working fine before, correct? By the way, you could try a server change at the Donation Checker to see if that has any effect. Make sure everything else looks ok while you're there as well.
You might do a corollary post in the Vixo 2 area further down the page to see if anyone there has a suggestion. In the meantime, I'll do some more thinking.
