Hello, I have experience VA say "Warning:The management node license is not installed. Most product functionality is limited until a valid license is installed." Then, I got another new License key from Virtuozzo Site and input. It got error message in below: "1602Cannot install new license: KA server failed (Another license is already active with the same HWID)" Did someone can advise how to solve it? Does VA is FREE or need to pay license fee? Thanks!
