I've had this happen once before, before Clockwork City. I couldn't log in for three months. I log in, get to character select, select a character and it sits at "Requesting Character Load" for about two minutes before it errors out and says "An error has occurred. Please wait a few minutes and log in again."
This has been going on for 30 minutes. It also happens across all four of my alts on my account. Please fix this so I can log in and play the game. I've restarted my client multiple times now, it did not help.
