Your welcome. What we need to know is where did you get the ship sets and EMP files from.
I am willing to bet that the emp files you have are not compatable with STOCK seiv, or not compatable with the mod you running.
Most mods modify files before making EMP's for their races. This devalidates those EMP's for use with STOCK games.
Vis Versa with EMP's made with STOCK SE IV Will most likely not work with a modded game.
Time to make new EMP's.
Try reading this tutorial -
Basic Modding 2
It may or may not give you some insight.
If you want Star Trek Ship sets and races that work in Stock SE IV click the link to the NASY (New Age Ship Yards) site in my signature.
Races that you find in the Star Trek Mod, or the AST mod will not work in stock SE IV.
