Trouble with Pahlava Reform

[TunaMaker]

So I'm playing Pahlava for the first time and having a blast. If I'd known earlier how much fun they were I'd have played them long ago, but was always intimated by the starting situation. I'm having a problem however. I can't build above a trader/trading post (lowest level market) in Apameia (I just don't have the option), so I can't progress to my reformed government. Anyone have this happen before? Also, settled aristocracy is not showing up in Hektamopylos (sp?). I followed the proscribed build pattern found here on the forums, and got as far as advanced settlement:

1.Military occupation.
2.Migration
3.Pastoralism
4.Large Nomad Market
5.Settled Community
6.Elite Herds -> Warlords Horse Herds
7.Reformed Pastoralism
8.Advanced Settlement
9.Settled Aristocracy
10.Reformed Parthian Government.

Anyone run into this before? Thanks folks.

EDIT: Both settlements are large towns.
