Hi Jayne,
I think it has been available all day, in which case it is either a problem at your end or somewhere in between you and the server. The easiest way to tell is to go to the page where it tells you about the P2P Enchange (
http://www.orphalese.net/p2p.aspx) and look at the number of decks available there. If the number is zero then the server is down.
Cheers
Richard
