Each time I start the game from today I received this message:
XmlException

Does this happen on all games, single/multiplayer? When exactly do you see it. If it used to work it sounds like something may have got corrupted so a reinstall might be best.

Happen immediately I launch the game.
I haven't access to the game.
I ll try again if not I will reinstall but I'm worried about multiplayer games I'm playing.
