Your serial number may not be valid for a few reasons. If your serial is for a network verison and you have installed as stand-alone, then your serial number will be invalid for activation. You cannot activate a network seat as stand-alone.
You will need to install the NLM and get a new LIC file, if you were hosting your NLM locally. If it was hosted on another machine, then simply reinstall as a network seat and point the client to the hostname of the NLM server.
