Are you talking about the Federation Ship Pack from Dystopic?
If so, there is a readme file with instructions (which also specifies that 'KHSM for DA' is required).
If you want to be able to use them with races other than Terran, it might work if you change all the S0_ prefixes to S99_
Thank you. First time anyones helped me on this forum.

Yes people do anwser if you give time usualy two days depending on the question there is a custom shipstyle guide found in the forums and yes you should need Kryo's for some of ships. if want to play with startrek ships there is a startrek total conversion found here in the forums.
As ive said above ive posted a number of threads on this forum and ive never recieved assistance - at least not with a couple of posts going "Hello? Any help?" over the course of a week.
I posted this thread 2 days ago now.
EDIT:
Ok ive done as I was advised but I still cant use the ships for my custom race Im guessing I probably need to create a Ship Styles xml file.
How do I do that? What do I do?
EDIT2:
Ok so I followed the "How to Add Custom Styles" thing...How I missed it ive no idea...
But ive hit a problem. The Ships i downloaded are retarded - they arent displaying correctly - they have been butchered.
Parts of the ships r missing. Or they dont look anything like they are supposed to...
What could be wrong? Anyone else got the Fed Ship pack encounter this?
