Forum:Problem getting DLC from Cerberus

Ok, I recently bought the game during the steam summer sale and after finishing Mass Effect 1 I started 2. I created an account for the cerberus network and downloaded a bunch of DLC, but Ic an't figure out how to get it to activate.

Whenever I start Mass Effect 2 there is always an error and I am forced to log in to the cerberus network manually, but I don't know how to activate my downloaded DLC from there. WHenever I start the game up it always tells me it was unauthorized and that I need to log in to activate it.
