Hello,
I also have a problem to get started with the World3 model in OMEdit 1.9.0.
- I downloaded it from https://api.github.com/repos/modelica-3 … ball/v2.0.
- Then I renamed the package.mo into SystemDynamics.mo.
- I opened the SystemDynamics.mo and stored it in the UTF8 format with OMEdit.

The tree structure appears in a window "Modelica Files". However, I can neither plot the flow-charts (only a circle everywhere) nor can I simulate ("Interfaces.RealSignal missing" or "Cannot instantiate SystemDynamics.WorldDynamics due to restriction PACKAGE".
The same issues occur when I follow the steps in the shell described in this block. I use Windows 7.
Could somebody give me a hint how to open the package and simulate a scenario?

Would be great!
