Oh then I know what the problem is: it was the antivirus. A lot of times, while you're downloading a game like this from the site, the antivirus blocks parts of the download. All antiviruses think that the cracks are malware since they are actually software that has been tampered with so they usually get blocked in the middle of the download and the game sends you to steam when you try to play it. The best solution is to turn off the AV when you're downloading the game
