I have no idea how you managed to fuck that up
twice, but let's just try to fix it.
Download
URM and put it into the game folder. Start your game, load a savegame prior to the 'in Bella's car' scene.
As you get close to it, in the top left corner you will see a blue overlay window saying "path detected" open it by clicking on the little button and a window will open, there should be 2 choices, one green, one red, the green being the one you are currently on, select the red option and close the overlay window - then save soon'ish after. That should do it.
