The crew for xbox 360 is not working, Why?

User Rating: 6 | The Crew X360
I installed the game in my 2005 white xbox 360. It is completely up to date and so is the game. I just don't have Xbox live Gold. I put disc one in and it says I need to do the download again. And disc two is an unrecognized disc. I deleted all things related to the crew including the title update. I re-download ed everything and same thing when I went to play it the next day. Again everything is up to date. Please give me some advicextra as to what I should do.
