Battlefield 4 BETA for Medal of Honor Warfighter buyers

[powdrilla]

So I bought MoHW a long time ago, when I bought it the online pass did not work however I remember I found a way to get the dlc to work, little did I know that that fix doesn't seem to have given me the bf4 beta that the code would have, I didn't know this until this morning, and I would really like to play the beta considering that most of the reason I bought MoHW.
Any help with this would be most appreciated.
