FYI: I checked server log for the recent 3 days (from September 1st) and found that there are no the update information requests with your license keys.
So I suppose that license key at problematic installation is empty (@printrbot, I saw your screenshot from URE settings page). Lets, re-check. If you’re familiar with SQL try to extract URE options from the WordPress database with this command (replace ‘wp_’ with your custom database prefix if needed):
select * from wp_options where option_name='user_role_editor';
and look for the ‘license_key’ string inside option_value field content. Is it not empty and does it contain valid license key?
