Mass Effect Trilogy-Missing Cerberus Code

Does the second laptop screen ever open for you??  On PC you have the one on the left that is for game options stuff and the one on the right is Cerberus network info.  From what I remember about PC the years ago when I was first getting this, if the second laptop didn't open(right Cerberus one) then the DLC wouldn't "authorize" and thus never be activated.  Mind you it only had to open once after the dlc install and not every game, but it did cause some confusion back when this all started.  Mind you, with all the changes it maybe all BS and such..

One thing to try is to remove everything, powercycle the game system(power off unplug and restart) redownload the game fully, redownload the dlc fully THEN start the play and see if it works.

IIRC the way to get the second PC to open was to enter your EA/Bioware ID/email.....sorry if that isn't correct, but it has been a LONG time since I have had to deal with it.
