I haven't played this game for a while, maybe 2 or 3 years and maybe i shouldn't come back.
This has never happened before to me, the game freezes when i press host game, when i try to join the game or when i refresh list. It freezes and says "Tennis Elbow 2013 v1.0i (not responding) and i have to quit the game using ctrl+alt+del to shut down the program.
