Log in problems first time

Hello!

I am a newbie to WP. Just made to downloqd the zip file correct to my webhotel. Was also able to start installing WP, choosed my username and password. When I pushed log in I got to a new page, al white and nothing happens..

The same hapens when i write my internetadress in the browser. My page show, and when I go to log in, I use my username and password, and the same happens. White page, and it seems like nothing happens. i was expecting to get to the main page to organize my new webpage.

What can be wrong? Every seems to me ok, but when I log in nothing happens. Just a white empty ?age appears.

Than you!
