So, I was playing fine all day today, and I just got randomly signed out. I tried to sign back in and it said, "Incorrect e-mail or password". No one changed my password because I went to my e-mail and it did not say I had a password change. I tried to change my password on mojang.com, but when I sent the e-mail to my account I did not receive it. I then changed the e-mail back to my original to see if I could change the password on this e-mail, but I still did not receive it. I have no clue what happened, it was working perfectly all day. Please help. Thank you have a great day.
