Problems with using downloaded cars

[GTP]

The game won't let me use downloaded cars offline. When i try using my profile offline it says i have downloaded content that is no longer available. My friend can use his cars offline but my xbox wont let me.
I don't have broadband so i use his connection. It makes me mad because his can play them but mine can't. If anyone knows what i should do can they tells me.

Its probably where you downloaded the contect from his Xbox live, Try goin into your memory settings and see if its under your friends name if it is then move it to a memory card and then back to your HD because it should change the name back to yours and you should be able to access it.

I had the same problem when I swapped HDs on mine.

Let me know how it gos....
