Thanks I have gone to the support area and asked them. My sons gave me the game for my birthday in 2010, the computer it was originally installed on has a virus and according to one of my sons, is not worth fixing. My new computer is a Windows 8 laptop and runs the demo without any problems. The main problem is that I have a large family (3 boys & 1 girl) plus my wife works out of our home. I have lost count of how often things are arranged, then rearranged. Especially after four years and two moves. I know it was not downloaded, it was boxed and had at least one disc. Nobody has a clue where anything is. I once had a job that gave me a crazy schedule. Now that I have some free time, 2 boys are in college, 1 is in the Navy and our 5 year old starts school in September.
