Only 1 network listed

Hi, I have had the old version of inSSIDer for years, I just tried to run it to check one of my networks that I use for CCTV and it only listed the network that is being used on my computer. I played with things for a while then went a-googling to find an answer and found the new version!
Downloaded, signed up. opened the app… still just the channel my computer is running.
I seem to be missing something, could you tell me how to get all the networks up please? Past experience tells me that there are at least 20 local networks.

…A few minutes later… it seems that my computer for some reason was only showing the network I was on rather than all the networks on the task bar… I got the others to appear on my computer and they appeared in inSSIDer.
Problem solved!
