Freelance 2019 does not work on domain-based networks?

Greetings to all; This week, upon attempting to start up Trados Studio 2019 Freelance I receive the message "The Freelance Edition does not work on domain-based networks". This has happened after my work laptop had been connected to the print/scan/copy machines of the company. Before - when my laptop was simply connected to the company's internet but without printer connection - I had no problems...does this mean that I must upgrade to Freelance 2022?
