Why did the game stop launching? (Sniper Elite V2)

Guys tell me why this game has stopped running for me? I downloaded it from a torrent from RG Mechanics, played it several times ... Now I decided to play it, but it does not react at all to the launch. I sinned that it was the Steam agent that was blocking it, reinstalled Windu to an earlier restore point, where I had not yet installed Steam ... and again the same reaction: I click on the shortcut and silence! I don’t see any sense in buying it, so that I can play alone a couple of times a year ... and in general I don’t like this idea with purchases on Steam, I bought Euro Truck Simulator 2 there, but I don’t feel the acquisition, the whole game is on incentive , and if this resource closes and there is no purchase! I understand to buy - you were given an installation file and an activation key, you install and play, not depending on other resources, but as if you were allowed to play temporarily ... If anyone knows the answer,
