It is hard to debug an older version of TDP. We are currently on version TDP 4.3.
i would suggest two things;
1) Download TDP 4.3 Trial and try that version. Save a back up of your automation script as it will convert to newer version.
2) Try using the embedded option. This will embed the export wizard file instead of linking it.
If either of those do not work you will need to open a support case and we can assist from there.
