Hi Unni,

those errors imply that the COM port number has changed, perhaps due to a Windows update causing hardware devices to be re-scanned. Check that the COM port number for your CAT interface is correct by locating it in the Windows Device Manager application.

Prolific USB to serial adapters do not store their COM port number and can potentially change just by re-scanning the hardware devices or by plugging into a different USB hub or hub port.
