I've been trying to login to the latest version of PRO ( v90_0) and been having some difficulties. I realize that currently the server is full, but instead of saying "server full" when I press login in the game, I press login and it freezes for a few seconds, then says "can't connect to the server." Is this supposed to happen when the server is full? (I am running Windows 7, if that matters) Thanks!
