How to Access My Password As The Administrator of Site

Good Morning,

My webmaster – Beast Graphics, is no longer able to assume his role due to other commitments. He terminated his working relationship with me and I know nothing about WordPress and cannot get in touch with him.

I forgot my password today and deleted all emails from him with my password. Can someone please tell me how I can sign into my website, in my role as the administrator and webmaster of the site. The page which allows users to sign in and receive a new password is not working and/or does not forward a new password to me.

I desperately need to get into my website at https://www.allparentsondeck.com and make changes to the Home Page.

My second problem is that the Flash File that contained the photos of parents and students is disabled and does not work. This problem is secondary to signing in and recovering my password. Your assistance with this problem is greatly appreciated.
