IE9 Convert to PDF button, Popup message: "Some of the content in this page was not available..."

I'm a PC user required to use Internet Explorer to access a specific website (titlepoint.com) for my business.  While using IE9 and logged into TitlePoint, when I convert a page to pdf using the toolbar button I receive a Popup window stating:

"Some of the content in this page was not available for download.  In some cases, this means that thte resulting PDF may not look exactly like the original web page."

I need to disable this popup - what settings do I need to change in order to do so?  I already changed the IE9 Advanced setting to include 'Disable script debugging (Internet Explorer)' and 'Disable script debugging (Other)'; would appreciate any insight available.  For further background I've tried using FireFox and Chrome to access TitlePoint and other sites, however when I export or print to PDF i cannot highlight/copy/paste text which is required. 

Thank you!
