Question : "Export Failed" in VB.Net and Crystal Reports 10

I have written a VB.net 2008 windows applicaton that allows the user to display, print, and export a Crystal Report 10 report if they chose.  All of this works fine except for the export.  When the user clicks the Export button (icon) on the CrystalReportViewer1 control, then selects exporting to a .pdf, then enters the file name, they get the following error messages:

Object reference not set to an instance of an object.
Export failed.

Attached is the code in the VB form that contains the CrystalReportsViewer1 control.

Thank you for the help.

I don't think a reinstall is needed but you may need to install the export dlls.
