More Babylon 5 mod problems! please help

OK. i recently created a post because i was having trouble with this mod. my problem was that i had never met a minor race on this mod (which has since changed), and that when i started a new game on the mod as the shadows, my favourite race, i didnt start with the ability to build shadow hulls. i clicked on 'new' in the shipyard, and the 'hulls' tab was blank. i couldnt build new ships! the only ones i had available were the orignal colony and constructor ships. this of course wont do if im going to rule the galaxy.
so, i got a reply from 'Rav8' who was very helpful. he sent me a file called 'logistics.xml to put into my 'data/techs/ file in the mod. so i put it where i was supposed to and quickly started up a new game as the shadows. im sure, although i may be mistaken, that the file had worked. my memory is hazy. im sure it did, but what i mean is that i may have gone to the shipyard, seen the contructor and the colony ship and thought ,oohh it worked. when i should have gone on 'new' in the shipyard. im fairly sure i wouldnt have made that mistake, but it is possible.
whether it worked originally or not, i have found just now that it does NOT work anymore. i havent been on the babylon 5 mod since so i didnt realise sooner than now.i still dont start with shadow hulls available!
can i be the only one with this problem? i hope someone can tell me what has gone wrong here, either something i have done wrong, or something wrong with the mod.
i dont know if this matters, but i did rename the file i was given, because there was already a file called 'logistics.xml' in the 'data/techs' folder.
i really hope that someone can help me out again, and thanks in advance to anyone who replies.
