GanttProject hangs and creates error log when I open the app

GanttProject is hanging when I open a specific project. Details: I purchased the latest version 2.8.5 and uploaded it to my MacBook OS X El Capitan (v10.11.6). I had GanttProject v2.6.1 installed previously. I created a new project in 2.8.5. When I went back 2 days later to open the new project, it opened but hung, and I received an error log (see attached). Any ideas what went wrong and how I can fix? Any help would be greatly appreciated. Error Message GanttChart.txt (6.4 KB)

The log says that something is wrong with your settings file. You can just delete it (all settings will be reset to default values). The settings file is /Users/TMarketing/.ganttproject

Thank you for your quick response! I can’t find the settings file /Users/Tmarketing/.ganttproject; is it a hidden file? What directory would it be in? Thanks again!

Yes, it is likely to be hidden in Mac OS. Just type /Users/Tmarketing/.ganttproject in the Terminal window.

Great - thank you very much!
