Never mind figured out how to do it on my own
Well, even if you didn't get help in time, sharing the solution can always help others!
Folder permissions within Program Files often screw with modding. So moving the game to another Steam folder outside of Program Files is a good first step. Then making sure the game is decrypted [typing IWANTTOFIDDLE (qwerty) / IZQNTTOFIDDLE (azerty) while in the game menu, then checking .txt files are now legible]. Then following the mod readme file thoroughly :)
