CoH: Modern Combat

I did that you told me, but I didn't get it, When I insert the serial, Steam say me that this serial is not correct... I think that serial it's being used. I've replaced the oldest files from 1.001 patch for the 1.002 patch but I see pink colour in the skins, I don't know what can I do . I surrender ...

If I'm not mistaken, I need the original game and a Steam account to play the patch 1.015. I have the game but I've downloaded it by internet and I have not a Steam Account.

Thank you friend, but I won't be able to play the 1.015 version because my game it is not the original, such a Shame...Thank you anyway.

I need help, I have downloaded the patches 1.001 to 1.014 but I don't know how to install them, Can anybody help me?. I'm really sorry if that is not the place to request help but I'm new, thanks you all.
