Internal Exception: Bad packet id ?????

I was logged in last night and everything was fine. Today i get this message:

Internal Exception: java.io.IOException:bad packet id ( then a number that changes each time i try )

Now it either crashes or gives me that message.

I am going to try and re download the game and see if that helps, but does anyone know what this is?

Thank you,

 

Update: Reloading the game did not help. Still cant get into server.

I am kinda upset if i cant play cause i just donated.. Should have had my new ability today.
