Error in Adobe download form

Question

Hi Experts,
             We are using Webdynpro Application with Adobe Forms for download the employee data we are using Print PDF form. Past two years it is working fine. But recently we got error while downloading the form. The system did not react and did not give me the PDF format. In the past I did not have any problem for printing them. I tried to several different computers and still not able to have claim in PDF format. Previously my Adobe Reader version is 9.1.0 now my version is 9.3.0 .
Form is developed in Adobe Life Cycle Desiger 8.0. Adobe Reader version 9.1.0 is working fine. But we are upgrade the next versions (Like 9.3.1, 9.4.2 and 10.0.) that time it is not working. Can you please suggest me. Where is  the problem.
Thanks in Advance.

Umang,
This exception occurs you are trying to add a child to a parent element not yet created. In your case vnAddress is the parent and vnData is its child if I am not mistaken.
So in your code you should first create an element of vnAddress and bind it and then create an element of vnData and bind / add it.
So your code should look like :
// Create and add parent first.
     IAddressTypeSelectView.IVnAddressElement  addressEle = wdContext.createVnAddressElement();
     wdContext.nodeVnAddress().bind(addressEle);
// Next manipulate with child.
     IAddressTypeSelectView.IVnDataElement dataEle = wdContext.createVnDataElement();
     wdContext.nodeVnData().addElement(dataEle);
