Forum:Me2 shadow broker dlc not triggering

I recently perchased me1 and me2 through a steam sale. me2 was the digital deluxe edition which comes with some dlc. One of the dlc is the shadow broker mission, which is the only thing that for some reason is not being activated.

I have redeemed one of the cd keys on bioware social website that has some weapons/armor stuff, but the other 2 keys don't work. When I log into the cerberus network in the game menu, it shows a little summary of the shadow broker mission (and the other dlc that came with it), which to me means that it was downloaded.

But it has not been triggered. I read that it is suppose to be activated after completing the Horizon mission, which I have done a while ago, there was no messege from cerberus, or any new dialogue with Liara. I don't know what to do. I payed for the game and would like to play the dlc. It seems there has been a similar issue with this floating around but I haven't found a solution that has worked.
