Why you broke a project? Last good version is 5-1-0. After that you get these "improvements and bugfixes" - no data import (why is it removed??); - every time you click on server name in server list in Modeler, it tries to connect to that server (if you accidentally click wrong server, now you must wait until it get connected or get error message - it's annoying!!) It's very good project, stay with 5-1-0 until these "improvements" is fixed.
