Hi everyone Bought a copy of UFO Aftermath a couple years ago, but installed it for the first time just now. My computer is relatively new, bought it last year, a desktop computer. I installed the 1.4 patch. I ran the game, but it insists on running upside down!! I read here in the forum the offered solution to change the refresh rate to 70 hz, so I tried, but it doesn't work! What can I do to fix the problem?! Any suggestions? Maybe I did something wrong? Is my copy of UFO bad? Please assist! Nitro
