I have been having problems trying to run games I have downloaded from this site. I purchased one, downloaded it and had no problems trying to reopen and replay the game. I got a couple of others, they download, I can play them once but never can open them again. I also noticed if I opt for the "Run" option I can play them the day they are downloaded but can't reopen. If I opt for "Save" and try to put them in program files I get a message about needing authorization and I am the system administrator. So I don't know what I'm doing wrong or different. Any suggegstions?
