Black Ops 3 Pirate Zombies Online - help

Just installed Call of Duty Black Ops 3 v100.0.0.0 + All DLCs [FitGirl Repack] launched it with ezboiii but is unable to as its an outdated version of BO3 it says.

Kinda lost on what to do now, any solutions?

I plan on wanting to play zombies online with friends.
