Design script stop working in Dynamo from Revit

Anyone have got the same problem? Just putting a simple codeblock in dynamo launched from revit it doesn’t permit to write any code inside. If i run the sandbox everything is ok. Maybe a package installed could give this problem. I tryed 0.9 and 0.82 with some problem.

Hi Neri,

It happens some times you need to Restart your Revit and Re-run Dynamo. Hope it helps!

I have resolved was something broken in my Revit 2016 installation, i have unistalled everything and reinstalled.

 

Thanx for your time.
