Lost wp-login!

Help!

I wanted my WordPress site, in a WordPress folder, to run from root, so I followed the indications here: http://codex.wordpress.org/Giving_WordPress_Its_Own_Directory.

However, I began by moving the core files to root (Root install) & copied & modified the root index file as indicated, rather than following Pre-existing subdirectory install. No problem, I just moved them back again & removed root index.php. But now when I access http://traduisons.com/WordPress/wp-login.php (displayed in basic html), it defaults to traduisons.com/wp-login.php (which no longer exists on root!) and displays a non-formatted structure of my WordPress site! Inherent links to themes & other core files seem to have been lost.

When I try traduisons.com/WordPress/wp-admin, I get this: http://traduisons.com/wp-login.php?redirect_to=http%3A%2F%2Ftraduisons.com%2FWordPress%2Fwp-admin%2F&reauth=1

I can’t even get into my Dasboard now.

Have there been some dynamic address changes that I need to correct?

Thanks
