@sebgg Have you tried restarting mongodb already? The restart button on the right next to the pencil button? Also, you can open the logs window right before you restart it and that will give the entire mongodb start up log.

This was sorted out by removing existing mongodb data and restarting mongodb. Not ideal solution for installation having existing data, but it worked for this instance.
