I have the PCM 2010 and it wanted to play online. I opened the GameCenter, updated to the last version and when I give him to enter to the room of the PCM 2010 it remains equal, the link does not answer. The same thing happens to me with other games of the GameCenter.
I have tried to re-install and nothing. I have an account yet and and I am login in Gamecenter.
Better answer I can give you, Buy PCM11 I'm not at home but i have PCM10 on my computer, i will try to open the gamecenter when i will be back to home.
