A new customer got stuck: PRO-SITES Question

Hello everyone,

I am a newbie and just signed up for the monthly package. I created http://kirmizihalim.com/ wordpress mu site (in Turkish though). Then I went ahead and installed PRO-SITES plugin. But now what?

I go to http://kirmizihalim.com/wp-signup.php and create a user, confirm the email etc. but then I click on PRO SITES link and the site says: Sorry, but it appears you are not an administrator for any sites.

If I login to the site with the new user credentials and then visit this page manually
then the site gives me the option to create a new blog as I intended.

Before the PRO-SITES plugin, WP MU dashboard used to have Create a New Site Option.

Can you please help.
