KX4Z Win10 PACTOR port problem

KX4Z -- last 2 weeks intermittent "port denied" on USB --> Pactor III modem.... suspect some problem with USB to serial converter, have ordered new one. Computer runs Windows 10, has generally worked flawlessly for months, now this problem. No problem at all with older VISTA computer that has USB to Pactor DRAGON modem in NCSHARES network.
