Hi.
I have now connected my OV301 to my PC and followed the installation guide to a fault. 
Still I can't get a connection between the oven and my PC. 
I have updated all drivers to the newest, tried to change the COM-port number to anything between 3 and 10, reinstalled CN7 software, reinstalled drivers, and I even changed computers.
When I try to connect from the "MONITOR" window, I get this message: "The configured serial port is not valid. Please choose another port." then I get to choose another, but theres only the one I configured, that is available to choose from. If I choose the same port I get 4 RED blinks from the USB connector and no reaction on the monitor. 
When I push cancel from that popup window I get this message:  the ComNumber property of the TApdComPort has not been set.

What to do?
Please help

My hardware:

Win 10. HOME
Intel Core i7-6820HK 2.70Ghz
16GB RAM
Nvidia GeForce GTX 1060
