Thank you for your response. Before I try your suggestion, I need to clarify that I am upgrading from version 2.5 to 4.0 pro. How do I proceed? Do I deactivate the older version first or do I just install the new one as you suggested? How do I get the files from the old version over to the Pro version? Is that the reason for the other two files that came in the zip with the purchase? Thank you for your help. I really need to get this resolved quickly.
