After moving Network Monitor to another server I cannot activate my commercial licensed version on the new server. The messages are: 'Activation failed.' and 'Activation: Check via activation1.paessler.com, result is \"License too old\'. Both servers have the same current Network Monitor version installed, but different Windows Servers: the old one has 2008R2, the new one: 2012R2. Network Monitor is turned off on the old server (Core Server and Probe Service). What can I do to correct this problem?
