I just completed the reinstallation of zen cart. When I attempt to login to admin program. I receive the message "Username or password are incorrect. I go to resend password and put in the email address "[email protected]" I receive the following message.
mail Error: Could not instantiate mail function. Please check Admin->Configuration->Email Options->Email Transport

How can I go to Admin when I can't get into admin logon?

I am sure that I put the right information in the admin logon. I cleared out all cookies and the cache.
