Game freezes when "Launch Game" is clicked on multiplayer screen
I recently obtained a copy of this game when it was post on sale by Steam last weekend. I started the game, and have played a few solo games and a few multiplayer games with a friend of mine. However, when we went to start up our multiplayer game no less than 2 hours ago it crashed when I clicked "Launch Game". Now, I can get into and load my single player games but for some reason my game freezes and stops responding when I click the "Launch Game" button on the multiplayer screen. I am currently in the process of re-downloading the game, hoping that it will fix the issue. Now, if it doesn't work, it would be greatly appreciated if I could get some help on how to get this game working because in all honesty, the multiplayer aspect of any game is always more fun than the single player mode.
Any useful information/help as to why this is happening would be most appreciated.
