Need help with MPL

[Kershu5]

I've managed to get a Mobile Processing Lab on the Mun as part of a Mun base contract. Done some science.. And it won't transmit at all. I've only got MechJeb and StageRecovery mods installed. I cannot transmit the collected /data/ from my MPL back to Kerbin. The current crew of the base is a pilot, engineer, and scientist (fresh off the boat ones). The base has plenty of power and four solar panels to keep providing more, it has /four/ DTS-M1 comm arrays on it. It refuses to transmit data. What have I done wrong, here?

Can you extend the comms arrays on their own?

[Kershu5]

I don't seem to be able to anymore. They're become locked. I can only extend them if I tell them to transmit science or data. Except they never transmit data..

You need to click the "start research" button on the lab's right click menu. That'll slowly generate science from the data, which you can then transmit; you can't transmit the data itself.

THANK YOU, this explains SO MUCH. Now I understand. Blarrrgh. Okay I can make this work then.
