we purchased the Engineerings toolset v 10.1. We added all our devices and in general works pretty well till this morning when I tried to use the network sonar. When I select it from the external tools / network discovery / network sonar it appears that its thinking about it but then nothing comes up. Is there something extra that I need to do to run this tool? I tried the other tools in the network discovery tab and have no problems running it. any assistance would be appreciated. thanks
