Text labels and graph gone

Hello everyone!

I have just started working with Space Syntax but for some reason my labels (text) and circles (result of graph), have disappeared. I could only see the TreeGraph at some point. I had an error in the beginning which I still do (see the Graph Link Comp), but at least up till some point I could still see the text labels.

Do you get the same error? Maybe this is due to some Rhino error?
