I recently purchased this game and cannot play it at all because it needs to be activated on the site. I was given no key and there is no link to attach or bind your steam account. Please help thank you.
Unfortunately you'll need to wait for a while before Steamworks servers back to normal. Also if you put Steam into offline mode or run PA.exe directly from installation directory game will work fine offline for single-player as long as your PC met requirements: http://steamcommunity.com/app/233250/discussions/4/619568793755951256/
