Hi can anyone help me out here. I upgraded my Nvidia 8800gtx to a ATI Radeon HD5870 at the weekend. All games running fine with the exception of COX. Anytime I left click on the screen, the screen flashes like there is an application running in the background, or like the taskmanager is open or somthing. After 5 mins, the game just plain disapears. No crash, no stall, it just goes straight back to desktop, like the game was never open. This is the same in the normal game, and in the test server.
Thanks for any info you might have guys, or some way to steer myself.
