I've been hosting a game that has unfolded over a period of days and one of the players accidentally deleted his save file for that game. He could not get back in to the game, so I emailed him a copy of my save file and my stats file, but he was still unable to get in. when he'd try to log in, he would show up on the game loading screen for a split second and then disappear. Are there any other files he'll need in order to get back in to the game? Are the save and stat files computer specific, so that they will not work on another player's computer? Or maybe the host file is different from the other player files, so the other player can send him his files?
