I downloaded Corel AfterShot 3. When I tried to launch it, it shows the pic of a girl with a horse then it says it has stopped working. I tried reinstalling it and choosing repair. It said it was fixed but same problem. So I totally uninstalled it and downloaded it again. reinstalled and ran it. Gave me the same message that it stopped working. Please help me figure out how to get it working. I use Windows 7 ultimate.
