Log-in fails, unable to re-set password

I have a new Runway install set up locally on MAMP, and the Log-in page looks fine, but fails with a message that the password is incorrect.

When I click to re-set password, no email arrives permitting me to do so.

I had installed a database from a previous Perch (not Runway) site. Would that cause a problem?

I have removed the setup file, and have the .htaccess file written as prescribed and in the root of the site.
