You'll laugh, but you'll have to replay this mission. When installing patches, you have to start the last mission you completed again; otherwise, the game will simply kick you out, or you'll encounter what you just described. If you really don't want to replay everything, uninstall the patches until you reach the version you used to play this mission. Complete it, reinstall the patches, and you'll be good to go! ;)
