State your platform and OS please if the below tips don't work.
Because I just tried this tutorial (I assume you're referring to the Global Conquest Mode) on a W7 PC and it worked. Granted the computer was a little specific on the position as I had to try twice to get it to work but if you just put your city pretty much right beneath the objective marker, just where the arrow points, it should work. The idea is that you have to put it so that the Northern German city stays inside the city radius. A similar thing happens in turn 7 or 8 but the same idea applies there, just put the base right beneath the arrow and you should be fine.
