Flightmasters everywhere won't let me fly anywhere.

[BegnionEmpire]

I have tried to fly to multiple locations in the past with the flight master, but the game won't let me. I have the correct amount of money, I have the location I want to fly to discovered, I tired re-logging, but nothing. The only thing that happens is that the screen freezes for less than an second, and nothing happens. Please help me, I'm tired of walking.

Have you tried any of the sticky thread suggestions? Disabling all your addons? Deleting your WDB and WTF folders? Uninstall/reinstall?
