Cannot use roles online

[skiabox1]

I have created a simple balloon site at my local pc.
I have uploaded it to 3 different hosting companies.
The site works fine except from its site admin pages.
I can't even login to them.
To login to the admin page I have created a user (admin) who belongs to the Administrators role and who has the password BalloonShop! .
I have run aspnet_reg to the database and then I uploaded using these instructions (http://weblogs.asp.net/scottgu/archi...nt-part-1.aspx ).
I can even see the tables online in the merged BalloonShop database that have all the roles and users.
Despite that I can't login to the admin page.
Here's my web.config file :


































loginUrl="Login.aspx" path="/" protection="All" timeout="60">







culture="en-US"/>



Any ideas on what is going on?
Thank you!
