admin login error

I followed the setup video ( http://demo.joomla.org/jumpbox.html ) on the joomla demo page and successfully installed and configured Sun Virtualbox.

Everything works fine until it comes to logging in as an administrator. I get the "username and password do not match" error. There's no option to set a new password

What do I need to do?

Same problem

HI, Can someone please help. I am battling with the same problem and as newbie has no idea how to reset password or fixed the problem myself. Thanks
