You will need to change the political party number to the next consecutive id number from the last one in your files for it to work fully. Use Galciv Writer to aid you in this. If you need any further help then please find me at The Galactic Core 

BTW you will need to go into the options screen in the game and enable the mods from there. Next time you start the game they will be there for you.

If you dont have a folder with the name 'mods' and the other folders inside as mentioned above, then just create them in the correct place

They should all go as above, The game will combine them again for you depending on what is needed to use them.
