I get this too. I can sometimes log in and pay fine, however soon as I log out or leave the game in anyway, the next time I attempt to log in to that toon (my main) i get 90k. It gets as far as loading me into the world, but when i get in the world is... at a standstill. No one moves, the recommendations list doesnt pop up- and after about 30 seconds I get booted with the 90k error. Swap to a different toon and it works fine.

SO FRUSTRATING
