Did you extract the files when you downloaded it?
When I downloaded the game, it first appeared as a zipped file, and I had to extract the files from it. Then I opened the extracted files, and I could open and play the game from there.
If that's not the problem, give a bit more information about what's wrong, and I'm sure someone will be able to sort it out.
