When i first installed i was able to go to the directory by typing in my url/wherever i saved it for example i made the folder shop and installed it so i went to Http://www.yourstore.com/shop

that all worked fine but when i went to login and typed in my usernmae and password on the site it didnt recognize either of them. So i tried to type in Http://www.yourstore.com/admin
that didnt work either. So i finally went through info to find out where to go and came back with this

http://yourstore.com/shop/admin/login.php

and username and password worked fine and took me into store settings.
