Hey I also have the same problem. When it checks my backupped cd it says "wrong key", but it work with the original cd. Thats kinda weird, but I think there is something missed on the backup cd what the burning program doesnt copy. So btw there are only 2 CD-Keys for Soldiers: Heroes of WWII. One for USA and one for Europe. I tried both. No success ... damn im still waiting
At least I try to disconnect my cd drives and try it with the image i made.
