A friend of mine had corrupted data for the extra missions. I had him delete the 2.0 update and now his data for the new modes are gone. I was wonder how I could get lost nightmares and desperate escape back.
I would start with Sony tech support- your friend's PSN account should reflect that he does indeed have Gold Edition- which comes with the missions.
I would think that Sony would honor this and provide new codes, but if not, you might just have to buy them =(
