Hi Pablo,
It sounds like you followed the correct process. I think this is a case where you should file a support ticket so we can prioritize and work on the issue more confidentially.
Here is a link to our ticketing system:
https://support.nagios.com/tickets/
Please submit a ticket and if possible attach a fresh system profile. For convenience sake you can just reference this forum thread or if you have the time a quick summary might be helpful for members of the team who haven't seen this thread.
Thanks and Best Regards,
Keith
