LICENSE REVOKED

1. Hello, I have a problem with the product license. I have a GRINDER server at home. When I enter the "BOS CONFIGURATOR" in Building --> License: it is revoked. I can not program anything, the KNX device appears as: connection error. I can not see the settings of the KNX device, nor any other device that I had previously configured as SONOS. I could have help in this matter, thank you very much.
