It appears to me too that whenever I update the stats, the game freezes until it gets it's results. I told myself this is probably because of either a slow server with an extremely high ping or the scoreserver is updating at the point when I was checking my stats. Now sometimes, like last night (Amsterdam timezone) my game froze for more than 5 minutes, which - in my situtation - was pretty unique. At that point also the forums were updated, so I guessed there was some maintenance going on. In general, patience is indeed the key... Keep in mind to give permittance in your firewall to let the game access the net.
