Mothership Zeta won't activate for me

[Shtingky & Shmellgy]

I got the game of the year edition, which states that all 5 game add-ons are included. I've found the crash site and waited day and night time for something to happen and it still doesn't. Anybody have any idea of how to fix this?

Are your DLCs enabled? Mine were not by default (no idea why). To check if your DLCs are enabled start the game launcher then click "DATA FILES" instead of "PLAY". If the DLCs are unchecked (disabled) check them to enable them. Your DLCs ought to be enabled now and the next time you play you should get in game notifications that the DLC quests have become available.

what he said. ^
if you don't have the quest log or the radio signals, you don't have them enabled.

There is a glitch where sometimes, if you install the mods before finishing the main quest (as when fallout 3 first came out, poeple had finished the main quest long before the mods were available) that some of the DLCs will not properly trigger. You can 'force' the quest using console commands.

coc 'insertcellname' - will teleport to a room. Get the code for the first room in mothership zeta. Not sure about the code to force a quest to start. I think it was something along the lines of player.getquest 'insert quest id'
