Hello, i'm really sorry you are having troubles running the game. I've added a step by step instructions to my page to help others if they are new to downloading games like this.
- One thing you might want to double check is if you have the right version (since there are both mac & pc options).
- Another would be, you have to extract the files to your computer before you start playing it, as some of the files won't run in the zipped folder.
I hope this helps! Anymore troubles please just let me know. ^^
