Network admin

Greetings

I wish to update to 4.2.1

it looks like after update to 4.2, I have lost the network admin right

when I do

<?php echo get_site_option( 'admin_email' ).'<br />'; ?>

it well return my own address, so I should be the network admin right?

so I can login, no problem,

on the upper nav bar I have the ‘my site’ drop down with the list of all the sites, but there is NOT the ‘Network Admin’ label in this dropdown

if I try a direct link like

http://mysite.com/wp-admin/network/

I have the following message
“
You do not have sufficient permissions to access this page.
“

so look like I don’t have this network admin right

How can I reset the network admin? or how can I change my own right to upgrade it to network admin thru phpmyadmin for example

Thank you in advance cause I am stuck for updating this network

cheers
