Cant login to dashboard

Hi!

-Fresh install on a bluehost shared account
-I have read the document with the proposed solutions. Nothing worked.

When i hit: http://www.mydomain.com/wp-admin i get:

http://www.mydomain.com/wp-login.php?redirect_to=http%3A%2F%2Fwww.mydomain.com%2Fmydomain-com%2Fwww%2Fwp-admin%2F&reauth=1

it seems that it redirects me to the real subdirectory where my domain has the files. To achieve this my provider instructed to use this htaccess on the root of my accounts directory:

# Use PHP5.3 Single php.ini as default
AddHandler application/x-httpd-php53s .php

RewriteEngine on

RewriteCond %{HTTP_HOST} ^(www.)?mydomain.com$
RewriteCond %{REQUEST_URI} !^/mydomain-com/www/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /mydomain-com/www/$1
RewriteCond %{HTTP_HOST} ^(www.)?mydomain.com$
RewriteRule ^(/)?$ mydomain-com/www/index.php [L]

any ideas?
