Ubisoft's put out word that any patches to Call of Juarez: Bound in Blood, made available recently, were "wrongfully released" prior to Ubi's deadline and are not the final version. That will be available "in the coming days."
Word of this passed in an "ALL MEMBERS MUST READ" message on the Ubisoft forums. VE3D, which noticed the message, advises "backing up your save files, uninstalling, then reinstalling in preparation for the 'official patch.' "
