[support] Backup and Migrate

[Roger]

I'm confused.

I wish to recreate our drupal 6.19 server web site on my  home pc.
I used Backup and Migrate on our server drupal web site and downloaded a 
copy to my home pc.

I read the Backup and Migrate drupal pages before proceeding.

I did a fresh install on my home pc of drupal 6.19 with a database named 
the same as the server database.
I used the same password and username.
Used Backup and migrate to put the data into the home pc installation.
Nothing worked, it was blank.
I logged out as administrator and find that Log in fails because it does 
not recognise the password.

What am I doing wrong?
How can I recreate an exact copy of everything, including themes, 
changes to themes, images and everything else on the server to my home pc?
Help much appreciated
Thanks
Roger
