hello, I'm having trouble. I bought empire at war and installed it without any trouble. I played it for a month so. Then one day, it wouldnt work anymore. Nothing changed between when I could and couldnt play it. As soon as I click start, the screen goes black and my cursor turns to an hourglass. I cannot close out and have to restart my computer. I have uninstalled and reinstalled several times, each without success. Someone please help!!
