I can't seem to buy anything from any market board

Earlier on I tried to buy some Wyvern Skins, and suddenly it stopped accepting my input. I keep getting locked out whenever I try to buy something as if I had tried to buy something that had just been bought that second, that happens sometimes. I thought it would fix itself, maybe just something to do with the new patch?

Except 10+ hours have passed and logging out, restarting the game, looking at different items, none of it works. I've had to have an FC member mail me things I need which is not convenient at all.

I've looked around and can't find anyone else who's had this error.
