I have trying to log into the Login interface that pops up after clicking the World of Minecraft icon, but i continue to receive the "Unable to authenticate" error. I have reinstalled 3 times now, did everything the tutorial told me to do, just incase I was doing something wrong. I type in my username correctly and I have changed my password 3 times as well, still no luck. I also installed the new version of java 64 bit. I installed this yesterday hoping to play, but the only thing I have got from this is frustration. Any help would be appreciated

I attached a pic to show the error
