    Help!  Adobe Reader 9 won't open a PDF in a browser window!

      I just "upgraded" to Adobe Reader 9 today, on my Windows XP computer.

      I run Firefox 3.0.8 as my web browser.

       

      Since installing AR 9, I cannot open PDFs inside my browser.  When I try, I get the following error message:

      "The Adobe Acrobat/Reader that is running cannot be used to view PDFs in a Web Browser.  Please exit Acrobat/Reader and exit your Web Browser and try again."

       

      I have made sure my Application settings in Firefox are correct, associating PDFs with AR9.

      I made sure "Display PDF in browser" is checked in AR9.

       

      I need to be able to open PDFs in my browser for work. How do I fix this error?

       

      Thank you,

      Ben
