My launcher fails to load. So i open MineCraft from my desktop and it loads right until the login stage. It just says loading where it should say play, It won't let me switch accounts, and i cant play. The launcher title for some reason is back to MineCraft 1.5. I have shut off my computer and turned it back on and it did nothing. Unplugged the WiFi and still nothing. Waited a day, and STILL nothing. I also looked up is minecraft down on Xpaw and it said everything is up. WHAT IS THE PROBLEM!?!?!?!?!?!?!?!?
