I need to open a MS Project file in JCVGantt. I tried two methods of importing; I exported to XML and also converted the MS Project file to Mindmanager 8 format.

When opening the XML file, JCVGantt just go back to the empty screen without opening the file. When I open the Mindmanager file, the information bar says 'Processing x/xx tasks', but then go back to an empty screen.

I am using the following:

OS - Vista SP1 (also tried it on Win 7 RC and had the same problem)
Project Professional 2007 (saving in 2003 format)
MS Project file - Project 2003 format

Any ideas will be wellcome.
