Moderators really dont help with tech support so your wasting your time hoping on them.
Going thru to tech support was probably your only option.
I hope they can help you but if the saved game you had reached their server it most likely has overwritten the one stored at Activision.
Best thing to do is save your games on the cloud as a backup.
Yeah, I was doing Campaign to get achievements I already had on 360. The thing was after halfway through the campaign. I saved and quit and all my progress on Hardcore and Rorke (sp?)files were gone. I don't know if they patched it today though. I don't see myself playing through the whole campaign in one sitting for these so I'll pass for now.
