Hello, today I bought a small dlc that was cheap for ac syndicate, and to buy it I've realized that I have sent an email with my bill (normal) and a serial number, by putting it to the beta of the Division IHe says: your code is invalid. I open wrong? or is it just the serial DLC? because it only came a key ac DLC syndicate, and down came a closed beta Messageto the division but did not come out any key, anyone know? I am clueless
