Funny thing is that that user does exist :P

Anyway, try puttng

javascript:(function(){var ls=window.localStorage;ls.removeItem('userID');ls.removeItem('userLV');ls.removeItem('userNM');})();

on your addressbar. This should clear that information and they should be retrieved again

Still getting the same problem :/
Funny thing that, my browser doesn't like the word 'javascript' so when I copy-paste the 'javascript:' part is eliminated, had to enter it manually.
