I just encountered this today and it's the first time it has ever happened to me. Not only was I not seeing the Play Now box, browsers set to open in the game client (Iron, CD and Waterfox) all wouldn't load and I would get a box saying Get Flash. The Adobe site wouldn't load-kept getting that Snap error. It didn't look like WGT was causing it, either.
After a call to the ISP help desk it turns out that in New York and Virginia, around 11 AM EST, there was some kind of server error causing DNS issues. Their message said some sites might not be accessible and provided a temporary workaround in a new DNS address. Problem solved.
I realize the OP is not in the EST but I learned something here about connectivity that just might apply.
