ok i think i have found the problem. i looked on my harddrive and it seems that downloading the free mission thro the in game download didnt download all the file (it had a yellow exclamation mark next to the file) i deleted the free mission and have d/l
it via the game addons in the market place will check if this has fixed it. gerblin i suggest you check to see if your dlc has the same problem. hope this helps
