Hi,
Is anyone else having this problem? When buying a game, the game won't download from the purchased page, have to go into your purchase history to download it. That's a pain, when you have hundreds of games!

Yes, other people have reported this and similar problems with the Big Fish website recently.

Unfortunately there's nothing you can do about it.
The problem is on Big Fish's end, probably related to their website being so busy.
There's nothing you can do but waste your life waiting around for it to get caught up.

I am not familiar with that problem, no.

But I am familiar with this problem which can occur when you have a large Purchase History.
