I have this client working on Steam. When I enter, I always come to the same splash with the fading "Press any key to continue"
The game also has its orange sign:
Server is full, Please try again later.
But I assume that in any moment someone gets out of the game, and when that happens, the sign dissaperars momentarily, the momment where the game should let me in.
I press furiously the keyboard (meaning that nothing works) and game doesn't do anything. I can access to the options though.
