Embedded Desig Control Libary 11.5 - Delphi Application

I'm developing a Delphi application using the embedded design component and viewer.

I've got most of it working apart from when I try and click the 'Save to Crystal Reports File' button on the embedded control I get an exception error. - Not sure how to get around this ?

Any one had experience using this component (either in VB or Delphi).
