anyone else got a problem with simcity's rush hour tutorial?

somehow i can't complete the rush hour tutorial. it's telling me to build a subway line from above to under ground, but when clicking the subway line button the menu just closes. it's not me, i've done this tutorial before and it's supposed to work fine. the pointing arrow is driving me mental><. does this mean i can't build subway lines in my own city as well or is it just the tutorial?

Hello,

If you know how the game works, why follow the tutorial anyway?
