Guestbook recovery

I've just added the 'Anti Bot test' to my guestbook and was so impressed with getting it right, that I decided to also add Email Encryption. The problem was that on the last two pages of code I had to replace, the code on my page was only 98% the same as on the instructions. I went ahead and replaced it anyway but unfortunately wrecked my whole guestbook. I thought perhaps if I download the guestbook again and just replace the pages I worked on (mostly templates)… but I think perhaps I made it worse. The error I'm getting:
"Warning: mysql_connect(): Access denied for user: 'antoine_agbook2@localhost' (Using password: YES) in /home/antoine/public_html/advancedguestbook/lib/mysql.class.php on line 30 Connection Error"
(http://www.antoineart.com/advancedguestbook/)

Before I start over, is there any way I can recover my guestbook?

Thank you,
Antoine

looks like you somehow edited config.inc.php. you need to put the correct database info in there. also guestbook 2.3.2 and later already do email encryption.

Thank you, Carbonize. So I messed up my guestbook just to add something that was already there? Silly, silly me!! Ayway, how do I put the correct database info into config.inc.php?

Thank you,
Antoine

For that you will need to either ask your host or look in cPanel.
