Maybe you should post this in Bugs and Fixes topic, where are listed the most common technical issues of updating and getting new demos.
I'd like to suggest you to check first, which version of software you're running right now. Then in Settings Advanced take a look, if the checkbox P2P is marked and mark it, if it's not. Then restart VGHD again.
But yes, try in Bugs and Fixes. There's the place where tech members meet.
