mustafa557 on "404 error"

I did for the first time install wordpress in its own directory and i did redirect the index.php to the main directory and i did change /** loads the wordpress.....**/ to the wordpress directory. so the url is now fine http://www.ulr.com without the wordpress directory. but once i change the parmalink to post name for the pages that i created, each page is not found right now.
Please help
