Here is a good question. I download game demos from Real Arcade and/or Big Fish games because I love to play the demos. After my time is up I uninstall them and clean them off of my system. If you try to re-download that particulair game it will say that the demo time has expired (usually 60 minutes is what they give you). I am curious...if I have deleted everything, how does it know I have already played it. The reason I ask is there is one game I liked. They came out with a "2nd version" of it, but it keeps telling me that that the time has expired. I haven't even played it. When I contacted the website they cannot explain and will not tell me how to fix this problem. I am also just curious how my computer has that information when I have cleaned everything out. I even will run the "Cleanup" program.
Thanks for your time.
