Windows errors port already in use Creality laser module 5 watt

I know its been asked but I have to ask again

I have the Creality laser module I got it out and tested it and it connected first time

it now shows in windows 10 in both LaserGRBL and lightburn that port 7 is in use and cannot communicate like its already communicating with the control box

Make sure you close both, then restart the one you plan to use.
