You may have hit a patch where you need to gain a level to get the next set of quests. I know there are some level 10 quests at Horizon in Western Thanalan. Make sure you're doing your Hunting Log, stop at every quest icon you see above someone's head, and jump in on every FATE you come across. I'm working on a secondary character right now and just got it to Ul'dah last night. In a couple hours I had GLA to 7 and THM to 11. So look around and make sure you're doing everything available. Turn on Recommendations so that it pops up every time you zone into a new area if you need to.
