Well, first off I've searched all over the internet and I can't seem to find any instances of my problem anywhere and I sincerely think that this might have only happened to me. Well last year sometime, my email was hacked into and the person who hacked into it changed the email, so when I tried to change it back it says that I can't (this is hotmail). Then I decided to try to log into my Minecraft account and it says "Account migrated, please use email as username", but as before my email was changed so it won't let me log in. When I try to change my password, I can't because my old email basically doesn't exist since the hacker changed it. So this about sums it up, I could use any help at all and would appreciate any information on how to solve this issue.
I just tried that, it requires me having an email address to even get into my Mojang account. So if my email address that is linked to my account basically no longer exists since hotmail won't let me change it back; I can't even log in to Mojang to change my email address that's linked to my Minecraft account. Thanks for the help though.
My old Minecraft account was: dag357
My new Minecraft account is: greenmachine5
