Elgg 1.11 install ended without access to admin

So I couldn't fix my older Elgg version so I decided to install a new 1.11.0 version, the install completed without a admin profile as I had surely assigned it a username and password during the install steps. My question is: how do I get a admin on the site so I can go to work? Also my 1st log in was from a spammer, how can I stop it's others family members from logging in without validating their profile?
