Drat! This just happened again, after 5 days of no issues. First time logging in on that account today. Crashed, eventually getting the "reset your password" message. Logged in on the other computer successfully, then back to the original computer. Remained in the same zone, Guild Lobby. Success! Really glad I have 2 computers. So what I seem to have learned is, resetting the C3000A "Cyber Security" setting will work for a few days. I guess I'll try doing that again. 5 days at a time is better than zero days.
