I feel like in a deep pain right now. Indeed, while i'm kicked most of the time when i'm not host, when i'm host the game crashes. I could however manage to play game when i'm not host, and the game didn't crash. It's weird, last time I tried to host the game seemed the freeze (on TURN 1 !), the music stopped, i could move the mouse but the clicks were useless. So I did a ctrl+alt+del and saw that the program was without response. When I switch back to the game, it was a black screen whereas I could still see the mouse cursor of Civ5 and move it. Is this something known ? How can I help myself ? Would upgrading to any expansion improve things ?
