Please share the source GanttProject file and the export result, and specify your MS Project version number.
Hi Dmitry
I get the exact same error as Pablo above, can you help me to resolve this?
If you need it I can share the source GanttProject file and the export result.

A solution reported by one of the users:
I think I have found a solution. I imported the file into an existing project in Project. That worked
Another option is to edit the exported file and remove a calendar with UID=2 from there.
You can edit it in any text editor. It is a simple hierarchically structured text.
