This is starting to get annoying, plz fix it.
I'm not getting the error this time, have you tried the usual things to fix it?
-Check and double check your username/passowrd
-Fully delete and reinstall the client
-Make sure that you are using java version 6 (NOT version 7)
-Use the resume button to take you back to the last server you played on if nothing else works.
Write back with your results.

Same here. It recently started today. And I followed your instructions, and it doesn't work.
Which one? Minecraft Classic or WoM Client. If you're talking about Classic, the website was under construction. But if you're having problems with WoM, I'm not sure what error you're making.
yeah im getting i think hat is the same problem except it says player doesnt excist and i know that my username and account for minecraft does excist and for here otherwise i wouldnt be posting this comment
I've had authentication error about half a year... There might be a problem with java, because i can't see what version java has...
I really want to play with WoM but it is just that damn authentication error that "stands in the way". Anyone plz tell me how to fix this (how I fix Java).
EDIT: Oh and i have played WoM for some months until it stopped to work because of that damn authentication.
Check your Java version HERE. You MUST have Java 6 not Java 7.
