Guild Wars 2

This is what it keeps saying in my trading post panel, and I have been trying for quite some time today. Seems like picking up cash works, but not browsing for things on the trading post or gem store. Anyone else have this problem?

Have you used the same instance of your client for the past 24 hours? It seems to be caused by minute changes in the TP or client. Even if you are kicked off the game back into your character select screen, it will not go away until you reload your client completely.
