Hello can someone help me i tried already with username and email but it doesn't work
Have a new password sent to your email. To do this, click on "Forgot password" at minecraft.net
That did not work
Why not? What was the message?
If i try to register with the new password there's still the wrong password or email address
Then you entered it incorrectly, concentrate more! If you set a new password, it works for normal then.
That was the right thing
Set when is that?
I'm sorry it's really super easy and what should I do - only you have access to your email so I can't do it for you. Do everything again step by step. The best thing is to take screenshots, which you can then send me via PM, maybe I will then notice what you are doing wrong. Maybe the registration systems or something were just down, that can be, but I think it's really up to you.
