updates??

I have 4 systems in my home (me and kids) We like to play COD black ops II on LAN. However with my jtag I cant seem to ever get the game version numbers correct. I do the updates to the game via title update downloader in FSD, but I cant seem to get the version numbers in the game correct so a LAN will be successful. Anyone have any ideas?? I hope I'm just missing something stupid

Thanks
