How can I get the last version of Need For Speed Undercover?

Where can I get the upload of Need for Speed?

I have the CD version of the game and I have reinstalled recently (some years ago I had installed the game on another PC, and uploaded with the new cars and the new modes of game, and I would like to recover that). When I select the option 'Upload' in the main menu of the game, it redirects me to the official web of the game but I don't found the upload there.
