system won’t remember email, username, password

I recently got a new host. They had me FTP my blog to a temporary sub domain. When I did this and attempted to log in, got redirected to “install”. A default blog was where my blog should have been. My hosts told me I neglected to copy mySQL in copying my blog files and lost everything.

I am now trying to start a new blog. WordPress won’t remember my email address, user name, or password. I get error messages no matter what I try. This is my third time trying to register. My email looks like this:
Someone has asked to reset the password for the following site and username.

https://windchimesusamade.com/blog

Username: admin

To reset your password visit the following address, otherwise just ignore this email and nothing will happen.

https://windchimesusamade.com/blog/wp-login.php?action=rp&key=FhYcs!DnOQ@u

I can’t get in to my dashboard and could really use some help on this.
Why would WordPress forget my data?

Please email me at [email protected] if you have any ideas.

Thank you,
Beth
