Idea..

[.: JaCkPoT :.]

I am currently after the cod4 map pack and i have a idea.. My uncle is away so i am using his account. If i go to his download history the map pack is still there and it gives me the option to download it again. If i download it to my console will that corrupt his one or will it work successfully?

I know people who have successfully downloaded the map pack to their HD using a friends recovered gamertag of someone who had paid for it.

So yes, it should work
