Get MOH:M Working

I know how to fix this, and here is how,

Can you not get your Medal of Honor Multiplayer working because of CD key error? I came across this error, and I found out how to fix it.

To fix this error, you will need to install Medal of Honor Single player. Also, you need to log into your origin(in game) after you install the single player. This is why your game is not working. This is pretty much it.
