Flight path broken

Hello. I'm new to the server, but not to the game. I unlocked the Stormwind and Westfall flight paths, but they don't work. I started in Westfall and tried to use the FP to Stormwind but no matter how many times I clicked the icon for Stormwind, nothing happened. Then I hearth'd back to Stormwind and tried to use the flight path to Westfall, same issue. The gryphon master wouldn't take my money (and yes, both times I had plenty) and wouldn't send me off. I tried restarting WoW and my computer. Anyone else experience this issue? It's kind of game breaking.

3 key questions:
1. does it impact ALL your char's flight points? only ones connecting Stormwind? only ones connecting Westfall? only the specific two nodes?
2. does it impact any other characters on your account?
3. which expansion are you talking about?

try clearing cache and WTF\account folders, then try again

1) I only have Stormwind and Westfall unlocked. I can experiment with another one after I get on.
2) This is my only character, so unsure.
3) WOTLK. Icecrown server.

I cleared cache and WTF folder, so we'll see if that helps

Hey. Im having problems with the flight paths in stormwind and duskwood. The game freezes when i try to use them. What can I do? I tried to clear WTF folder and cache
