The game stores the population in many ways and addresses. Note that changing the population is mainly for unlocking achievements and some other things (like increasing Ship limit and Military budget). The trainer is for playing WITH the addon (Venice). That is an entirely different version of the game. Play Anno 1404 - History Edition (start without addon) When you launch the game on STEAM (for instance), select: This trainer is SPECIFICALLY for the version of the game WITH the ADDON (Venice).
