I have recently read that several players on the forum have been unable to complete this quest line, which possibly suggests there is a bug.

Unfortunately several players have reported problems on the EA forum with the Acorn Kirk quest line (parts 2 and 4) and haven't found any way to continue the quests so far. I have added it to a BUGS AND ISSUES thread in the hope that EA will provide a solution for players stuck with this quest.

Players have also tried storing Kirk and the Van Houten house and even reinstalling the game but the quest is still stuck.
