launcher is 1.6.61

recently bought and downloaded minecraft for 28 dollars
bug since the first launch!
it does not let me get into the world... it loads then immediately closes exiting me to the launcher. this needs a few tries to get it to work properly which is not of quality. sometimes like today that it doesn't even work even after a few tries...
secondly, why should I make a new and separate account for reporting bugs on my minecraft other than my original minecraft account??? that's bs
lastly, why is minecraft for windows 10 only available to Hotmail users?? that is not fair considering the price I paid!
I expected better for a game so well known and expensive! Please fix or refund!
