It will always work (if you do it correctly) in any PBW game that uses stock SE4 or a mod that does not change the racial characteristics or advanced traits.
1) Load up SE4 using USM.
2) Create an empire.
3) Hit begin game.
4) Hit the process turn button.
5) Save your empire file.
6) Send it in.
This will give you all the strategies that are in USM. Additionally, it will let you make use of the other eye candy text files in USM (such as Demeanors.txt, EmpireTypes.txt, EmperorNames.txt, etc.).
