close out of the game and restart origin, sometimes it starts the trial even w/ the full game unlocked. happened once to me
need keys, where to use them, savegame, instructions, blah blah
I need to find them first hahaha If ANYONE has a save game with the Remnant Decryption Keys PLEASE upload the save file and where you found them.
I am pretty sure that they are dropped from the Remnant at this point. Not sure if you can get them anywhere else.
