Okay, so my friend put together my new computer while I was away and decided to test out it's power by installing a store bought copy of Shogun 2 on the computer which I had bought. Apparently in order to try the game he also needed to get steam. So he did, but he didn't enter in my steam account he just randomly made one up and started the game up on Steam. So now I try to play Shogun II on my original steam account on the same computer but when I double click on the icon it just takes my steam program over to the web page where you buy Shogun II. So my question is is there a way to transfer the Shogun II from that account over to my real one or am I screwed?
