Help me get my gallery2 back please!!

Ok, my gallery2 used to work, until my hard drive failed and I lost everything...

The thing is that my OS Ubuntu 8.04 runs on the first hard drive /dev/sda1 but my home directory where I run everything runs
off of /home/* which is on a different partition, on a different drive /dev/sdb1

So I got a new drive for the OS and re-installed it, then I edited my /etc/fstab file so that /home again is on /dev/sdb1

All of this runs well, I edited the config file for apache2, and it is now pointing to /home

My gallery2 setup is as fallows:

My root for the apache is /home/raymond/www

and gallery2 is installed in: /home/raymond/www/gallery2

and the g2data is in: /home/raymond/g2data/

My database is in /var/lib/mysql/gallery2 and I copies my backup of the database file as far as I know that it is:

4 drwxr-xr-x 2 mysql mysql 4096 2008-05-25 16:00 gallery2

anyways, I am not sure about the permissions or owners or groups on that file, because when I try to browse my gallery via the
browser I get this error:

http://myhost.net/gallery2/main.php

An error has occurred while interacting with the database.

So I am not sure what I need to do, and like I said, since only my main disk went bad and not the second hard drive where I have
my /home mapped, all the data is there and for the rest of the OS, I backed it up.... So if I am missing something I can get it from the backup, I just don't know what it could be. I have the configuration files, everything for gallery2 in /home/raymond/www/gallery2

Please someone let me know what I should do.

Thanks a lot!!!! ahead of time.
