Hi, all.
I'm playing rtr vll as greeks. I dont know how it works so let me ask for help. I have been upgrading "stages" and building some military buildings but still cant I train anything. All is stuck at the same stage as at the beginning of the game where I was able to train some units.
Can anybody please explain to me what the hell do I have to build to finally be able to train anything?????

Thanks in advance
