Starting this morning I have been getting crashes every Singleplayer Session mission I try. I've played it for two days without any problems, until this morning... It happens when I have a target locked up and fire an AT missile. The mission then crashes. That's the mission not the game. Has me stumped! I haven't changed anything on my computer since yesterday, just put it in standby. The only thing in game I've changed was the water, from High to Normal. I've put it back and no difference.I've rebooted, closed all running programs and it still crashes in every single mission. I've tried dumbing down the graphics, I have nothing overclocked, just isn't making sense to me. Any ideas? Here's the last crash file I just got attached. Thanks. DCS-20081224-015740.zip
