Please help!!

come on guys,i don't think it's that hard,just tell me(it is the spoiler tread,isn't it).At least tell me in which system is it and how to get to that system!!!!

i have a question.I was in Ptah and found the last datadisk(or blackbox,forgot which one)that says i am supposed to take it to the nearest colonised station.Well i did it and sold it there but nothing happend.What should i do after that?Is this the end of the quest??Is there another thing i should search for or do??
