WPMU Dashboard - A 2nd admin has no access to the dashboard

Hi, in the last hours I replied twice this post but I don't get any reply, and it's an issue from your your plugin.

Can you help me please?

I need to give access to a secondary admin and after updating wp-config.php and confirming that user is listed in dashboard - manage:

Only the admin users "admin", "Admin2" have access to the WPMU DEV Dashboard plugin and features on this site.

I still can't see the plugin in the #2 admin panel.

I also get a "You do not have sufficient permissions to access this page" error accessing directly to the URL.

Please help.
