Harmony 12 demo problem (no network view)

I’ve had to install a copy of Harmony 12 (demo) I open Stage Advanced and open the project I’ve been given and I cant see the network view. I’ve tried removing the demo totally, I’ve reset the workspace and I’ve looked at adding a new tab to just about every place I could its like its totally missing from the software.

I’m totally out of ideas and I really need help!
