It has only been on steam for two years so you bought a disk version that long ago. When Steam got access to sell and maintain sales of Kohan, they did not get the keys and had to make thier own. Your key wont be registerable (dont know if that is a word, but it ought to be if it aint! lol) for steam. I had all my disks stolen recently so I have been replacing my games while they make it to be on sale on Steam. I had a list of CD keys and asked the same question to Steam support. I would have just downloaded the .iso files, but without proof I bought each of those keys even though they had never been used by anyone but me it would have been considered illegal by default. So I purchase everything again...

ahhhh i see thanks for the info man.
