Wordpress install problem /will not send password

After doing the “advanced” one-click Wordpress install, I try to register the blog title and e-mail adress. The page then starts to load, and never stops. If I refresh, it tells me Wordpress is installed, but I haven´t got any password. If I try to get a new password sent on e-mail, nothing happens (except the endless loading). I have set up a new database and host for this.

I have also trouble retrieving the password from one of my previous installs.

What seems to be wrong, and what can I do about this?

Remove it and reinstall.
