So I completed the quest " A brain's best friend" I distinctly remember picking up the audio file as it is part of completing one of the quest objectives.

Talked to Dr. Borus, completed the quest.

Then went back to jukebox to load up the file onto the sonic emitter but I don't get the option to load up the file.

Am I missing something?

Hmm... this DLC is pretty new and bugs are being discovered every day. I would try these things to see if they fix it (no guarantee):

1. Try talking to him again, it actually helped me once.
2. Reload, and talk to him again
3. Reload in the X-8, reacquire the schematic.

Hope this helps. Good luck!

You have to tell him you got more audio tapes for him. I think you have to turn off and back on their personality's via S.I.N.K (the big circle map). Like re-booting a computer. I had the same problem

ahhh maybe that's the prob, I turned off the personalitys cause they were getting annoying, except for lil muggy that is . Let me give it a try. Thx for the tip.
