Query: WA Incorrect Key Codes

The game is nice.I also got a 16 digit key code for Winter Assault (and it is asking for a 20 digit key code). I saw on a forum that it works if you insert 0000 in the first box. It didn't work for me but when I inserted 0000 in the middle box it worked. Play around with the 0000 before you return the game. It might work.
