What does There is insufficient cached information to determine the next network at hop # mean?
When DesktopPerspective successfully traces to a location, it saves that trace information — so that if you trace to the same location, and you do not reach the destination, DesktopPerspective might be able to tell you what the next hop would have been — allowing you to figure out that a router is down. So, this messages means that DesktopPerspective does not have a prior trace cached to tell you what the next hop should be.
