Both myself and a client are experiencing the same error message when creating a new Project. "PRT failed to generate". The problem started occurring after the March release of Urban.
The error message occurs between a few seconds to 1-2 minutes after a new Project has been created. We have not done much there yet, just clicked around, opening the Development pane for instance. I've included a printscreen of the console. Please contact me if you need access to a model, where the error occurs.
