There are three situations where this error is shown:

  1. You're trying to open more simultaneous instances of qbase+ than allowed.
    Solution: Close an instance of qbase+.
  2. qbase+ did not shutdown correctly due to a computer crash.
    Solution: Wait one hour until the license server releases the license. If you can't wait you can open a support ticket and one of our agents will to solve the problem on our side.
  3. qbase+ was unable to complete the login procedure because your computer is behind a firewall / proxy server.
    Solution: Provide proxy server information or add exempt rules to the firewall. Your IT-department will be able to help with this.
