Problems with Crossfire Storyline

Hi again,
well i'm kind of stuck in die crossfire story...

I found the 9m cash datadisk, the sleepership, earth and even managed to get a further mission assignement from the corsairs (only telling me about find the sleepership -.- btw... why do i have to go to omicron gamma just to get this info about it, which you also get on planet crossfire.. ). Well now i'm propably supposed to find the 3 pieces of the map to altair but isn't there any hint where to search for them, which i am missing, or do i really have to look trough the whole galaxie?...

Well i already searched in the forum but there's always written "follow the instructions", but the only thing the datadisk tells is that there are 3 pieces...

Thanks for you answers,
Nem-

Well i found the jumphole without the disks but i've still no clue where to look for them...

Is it possible that the mission assignments are missing somethings? the one on earth was cut in the middle of a sentence and i only found the clue about omicron gamma here in the forum. the one at the corsairs is extremely short and without any usefull info.
