If you are trying to do a php include so that the guestbook is part of your home page. Please do a search on the forums. It has been discussed many times here.
Use the default login and password which is test and 123. Then go in and change them to whatever you want. Also reading the FAQ page that comes with the guestbook files would have told you this.
Ok you dont use the password that got you into your guestbook. You use the password that and login name that gets you into your cpanel that your host gave you. I take it you are just going to over right the old database. If not then you will need to create a new one and enter the name of it in the correct place.
Would you happen to have a copy of your old config.php file still. If not you need to fill in the blanks for your new config file. Below is also what you will need to add into the install.php page when you bring it up.
