Connection was reset - cannot access phpMyAdmin (no replies)

I installed this and everything seems to be working.. I followed Quick Start guide in the dashboard, but when I try to access phpMyAdmin or hello.php, connection is reset.

What do I have to set? I'm kinda newbie and never installed webserver..
I only need it within my LAN and only need MySQL - for testing of app I'm making..

Thanks for any advice... :)
