Help with can bus analyzer

I am in the process of sniffing my cars can bus to do an ecu swap and I have the can analyzer but I seem to be having a hard time getting it all to work I’ve downloaded all the drivers and software it was able to run the self test but also the lights do not come on for the tool itself. This is all very new to me so any help is appreciated.

Also I did the loop back test and it’s only showing a frame was sent and nothing was received.
