I made the mod using the original FIFA 18 version. Since every have so many different versions. You may need to manually import all of the files in CG File Explorer if you get any errors. It should take like 5-10 mins to do that.
Normally when a patch doesn't work, it seems you have either the wrong game version, no permissions for the drive or the folder where you game is, or you didn't setup CG File Explorer or Frosty Mod Manager right. Try going through different version and see what works.
