Problem with nuance PDF preview.

Hi everyone,
I am using Nuance PDF viewer on my Windows XP. I used the nuance PDF preview for PDF files. It was working perfectly few days ago. I have also installed Nuance PDF Toolbar plugin. Now recently I have updated my Internet Explorer from version 8 to newer version 9.
My problem is that whenever I tried to create a PDF file using the Nuance tool bar plugin, my I.E9 got corrupted. It stops working and hanged for a long time. Please help me how to get rid of this problem.
Your suggestions and tips will be highly appreciated.
