Stuck on Mantis

Can't go to Koboh, because error message "The game needs to download and install the latest patch in order to proceed."  Also no holomap.  Uninstalled, reinstalled several times, from disc.  Each time game was completely downloaded, all updates are current.  Have over half storage space still free.  Have looked at other discussions on this, with no answers.  Seems to be a continuous problem.  Can anyone give me a solution, please?
