Content i downloaded all the cod waw map pack then i made a new account and even tho they are saved to my hardrive i cannot use them? what do i do xbox is my life!

It's to do with the License type on the content. Some content is only usable by the profile that was used to purchase it. Some content is usable by all the profiles on a hard drive.

Try using the first profile (the one you used to download the maps), and see if you can access them that way.

Same thing happened to me. i called xbox and they did nothing for me. you are going to have to buy again. but with the new one coming out so soon YYYY???
