I have 2 problems with BF BC2

First: about half a year ago on some of the sales in origin, I bought BF BC2 digital deluxe edition. it consisted of addition of Vietnam. the game itself is running with no problems, but the addition does not want to activate. (requires a key, I enter the key from the digital deluxe edition, but did not activate)

Second: recently reinstalled BF BC2. then I went to the game and accepted the terms of the agreement. then I was asked to enter the serial number of the game, which I did, what I got out a message saying that the key is activated (by me also, as I have already played it)

sorry for my english. just the whole text has been translated in google translate. and help me with my problems, please
