Well first off when i played need for speed: ProStreet, i downloaded some of the cars and performance packs, and i WAS able to play with the packs when i wasn't connected to Xbox live, now everytime i go on the game, it says '' The film you are attempting to load is of a version different than your current game title. An update to your game title may be available. (Visit NeedforSpeed.com for information)''
This only started to appear when i have downloaded this content again, and i have to connect with xbox live to play it, but before i didn't have to.
This also is a problem with some of my arcade games, including: Trails HD and A Kingdom for Keflings.
Please Help, Thanks :)
