Hello and welcome Derek.
You're correct of course about not being able to use scanned document PDFs with Monarch. If you try to open it with Monarch you'll see nothing but a blank box with the PDF Import Options dialog.
You might try applying the [URL="http://www.datawatch.com/_support/downloads_updates.php"]9.01 patch[/URL] but I fear that it won't do much for you in this matter. It's probably a good idea nonetheless for other Monarch work.
Send me a PM with your email address if you'd like me to try your PDF file with Monarch v10.5.
