Well thats one reason why people aren't unlocking them after the xbox.com site was updated but doesn't solve why I can't get them again as I haven't got any of the MP achievements.
I do hope they have good news for me on monday as the DLC is no good if I can't reunlock the achievements again.
I could earn the achievements on my other gamertag which I played on after the xbox.com update but before the update on my main account the achievements weren't being added to my gamerscore so when I recovered my gamertag the achievements were gone which I new would happen so I cleared my cache,so I could play those chapters again but I couldn't unlock the achievements again as something must of got screwed up between my gamertag and xboxlive.
