I quit and restarted Minecraft because it was being slow/lagging a lot to see if it would help.
Unfortunately, when I opened it up I was logged out and every time I try to login it gives me this message:
Username or password incorrect!
So, I re-typed everything and made sure to type it all correctly and it still won't let me log in. I also noticed that as soon as I hit login the password becomes blank.
I have purchased the game so it's not like a trial has expired or anything like that. What can I do to fix this?
