Hi,
Sorry to hear, you're facing these troubles. Because of the WSAETIMEDOUT 10060 Connection timed out (A connection attempt failed because the connected party did not properly respond after a period of time, or the established connection failed because the connected host has failed to respond) error you get, it looks like a connection problem (most probably caused by a firewall/anti-virus blocking it).
Please, double check again all firewall/anti-virus solutions you are using - the port 16720 on your license server & all involved computers have to be open both for TCP and UDP.
Best regards,
