Downloaded backup & my account was reset but..

I can't sign up.

Is there an error that came up or screenshot you can show us?

You should have gotten an invite email you have to use to sign up again. You can't sign up through the normal signup button.

Check in your spam folder for it, and if you still can't find it we can resend it.

 I just resent it anyway because I realized your account was reset 8 days ago and the invite expired...
