Try first this: * delete the configuration you created * open a file in your project, right-click in it and choose Run as -> Erlang application
This will create a configuration that should work. You should see a console opening, where you can interact with the Erlang node.
If that is not happening, please go to window->preferences->erlang->report problem and create a report. Attach it to an issue at https://github.com/erlide/erlide/issues or send it to erlide_bugs@lists.sourceforge.net
