Plutonium

i downloaded waw with buzzheavier on steamrip and i cant play it on plutonium, everytime i try to load t4 multiplayer or zombies it says "patch.ff not found".
the game itself works fine, well kind of, the multiplayer and coop doesnt work, it asks me to make and online profile and everytime i put a name it says 'profile could not be created, and for some reason i cant start the game i cant start the game from the desktop with the exe file, it has to be from the games folder. the campaign, nacht (i didnt get any dlcs), the console and everything else like fullscreen works fine.
i tried reextracing the rar files from the website and reinstalling them multiple times and it was the exact same, i installed bo2 and bo1 from the same website and i had no problems, other than bo2 which had me reinstall it and the game is in italian, moist voiclines are missing and the rest are just in italian, but no problems with plutonium itself. also, waw doesnt pop up for me on steam or epic games.
can someone tell me how play the game with plutonium or pirate a copy with dlcs?
