That's weird, have you tried downloading it again ? I just donwloaded it and launched it and it worked. I know I some times get a message but I just click okay then it's fine. Try redownloading it (If you're motivated) and see if it works ?

Yes, it had happened the first time I loaded the game, I retried, and it worked, but my computer couldn't handle the graphics, after that I made my first comment and deleted the game. After you told me about the settings, I redownloaded and tried the game, but the same error happened several times in a row. I'll mess around with it some more.
