Unrecognized task serialised by server;missing registration

I switched from the CA server to the TX server and it's working now... finally after doing everything short of reinstalling PoE.

Received the Unrecognized task... error this evening. Tried to log to another character and received the error. Created a new character that successfully entered the game, logged out to character selection, and selected my desired character to receive the error. Changed from The Texas server to the Washington serve and the error went away. I was able to go back to the better latency Texas server with no error.
