Problem with mpp file import

Problem with mpp file import

Hello,
i've been having an issue while trying to import a project file.  I'm not sure exactly where the problem lies so let me describe in detail.

1.  Using OpenProj tool i created a project document with a gantt chart.
2.  I saved the document as "Microsoft Project Document 2003" format, which OpenProj saves with the .xml extension.
I rename the file to .mpp extension.
3.  Tried to import that document into Zoho projects
4.  Then i get the following error message:

Import Microsoft Project Plan(MPP/MPX) Wizard

Problem while importing !!
  • Assign all tasks to 'Unassigned' who is available in DZ Card
  •  Map the assigned 'Mpp Users' to Projects User.
 

Clicking on "Continue" does not do anything.  "Back" takes me back to the file selection.

The most confusing part is that there are no resource assignments in the project file at all.

Any suggestions would be greatly appreciated.
