Do you play using Knossos?
If yes, can you please run the mission using the "Fast Debug"-option. You just have start the mission and can close the debug build immediately afterwards. Once you have done that, use the "Upload Debug Log"-option and post the link provided please.
That should provide most of the information required for a perliminary analysis.
EDIT: Following reading your other post, as you are unfamiliar with the franchise:
The Return to Base-conditions are a bit strange if you are unfamiliar with B5, as it tries -as best as was possible back then- to simulate a B5 style shared jump. You have to close to Yorktown and face towards it before your jump drive is unlocked.

Got it to work. I had to get close to the ship before jumping to hyperspace. I wish the mission had a prompt to do so though.
