PDF does not open in IE 9

After installing PDF Architect I am no longer able to open statements and Trade Confirmations in the Wells Fargo Advisors (www.wfadvisors.com) site. If i uninstall PDF Architect then the documents open properly. I have uninstalled and reinstalled PDF Architect and still get the same results.  I have Adobe Reader 10 on the PC. I am running WIN 7 Home Premium.
