Not able to develop app in desktop modeler

i created an app on web and now want to proceed working on it in desktop modeler. The modeler opened and started app downloading, it seems stuck as the downloading is going on for 1 hour. It is neither allowing me to stop it or work in parallel in desktop modeler.  I tried twice killing the app. No luck.  kindly suggest.

You can check the logs of the Modeler. In the Help menu, choose “Open Log File Directory” and then open log.txt. Do you see any strange messages there around the time that you were trying to download the project?
