Remember: The code is just a gateway. The real "extra quality" comes from the mods and fixes that let you experience the Los Angeles invasion the way it was meant to be played—on your terms, with no DRM holding you back.
Sometimes, deleting specific license files can force the game to re-verify. Check your ProgramData folder (ensure "Show Hidden Files" is on) and look for lingering .dlf files related to the game's launcher.
