My server has broken and I've restored a backup on a new fresh installation. On my old installation I has 5 technician but now the problem is that after restore the backup I have a big message that says:

 "You have created 5 technician logins, But your license can support only 1 technician logins. Please perform one of the following for continued service.

Remove unwanted technician logins and restart the application or Upgrade your license".

How can I solve this issue?

Thanks!
