Forum:Activating Cerberus network halfway trough the game

I recently started my second playtrough (just finished the horizon mission on insanity) when I decided to buy the cerberus network content (I have a second hand copy of ME2).

Am I able to trigger the cerberus missions from where I am now or do I need to restart the playtrough? Since I am playing on insanity difficulty that would be most annoying.

Thanks
