Homeworld 2 adding new race issues

[Peacevan]

I am trying to add another race to homeworld 2. I have more than just triple checked the family lists, Race.lua, the starting fleets, and the build/research luas for my respective race. I have already attempted to solve my problem on my own and look up related problems on the internet but nothing has worked. I have a buld capable capital ship, a frigate, and a fighter squadron that all work fine when given to the Hiigarian starting fleet however when I try to play as the race in question the game crashes with this error report:

Killing player 0 (P) at time 0.100000
GameObj: Error: Level has ended on the first frame. Game rules (lua) has determined game is over. Level may have no ships. -- FATAL EXIT -- gameobj/839:! --stack trace-- 0x004946FC: GSLobbySessionDesc::operator= (C:\Program Files (x86)\Sierra\Homeworld2\Bin\Release\Homeworld2.exe) 0x005AE71A: getLibraryID (C:\Program Files (x86)\Sierra\Homeworld2\Bin\Release\Homeworld2.exe) 0x00491221: GSLobbySessionDesc::operator= (C:\Program Files (x86)\Sierra\Homeworld2\Bin\Release\Homeworld2.exe)

It's difficult to say what exactly the problem could be.
Do you have a modified deathmatch.lua?

Have you tried removing all ships from the hiigaran starting fleet EXCEPT these ships you are testing, to make sure that the game does, in fact, recognise them as build capable?
