The things you can do:
1. Contact the makers tech support dept.
2. Return the games to the shop and ask your money back because they don't work with you (and even the makers tech support can't solve it).
3. See if it works after a clean install of your OS. That's likely if it's a software issue, but just as well it's your hardware (like graphic card) that isn't up to the task.
