It seems like there is a problem with the "Energy Analysis Package"

@mahdino2000 just wanted to know if you are running Dynamo on top of Revit or just a standalone. Energy Analysis package has a dependency on Revit, so you need to run Dynamo from Revit application. If you are already running it on top of Revit then this looks like some other issue.

[epeter-]

maybe try zoom all. if you have older definitions they will not show on screen as screencoordinates have (obviously) changed

Closing as this issue is for an outdated version of Dynamo. If this persists in 2.0.x for you, please feel free to reopen and update accordingly.
