Trouble viewing PDF files
Many of our files are PDF Portfolios. A PDF Portfolio contains multiple files assembled into an integrated PDF unit. The files in a PDF Portfolio can be in a wide range of file types created in different applications. For example, a PDF Portfolio can include text documents, e-mail messages, spreadsheets, CAD drawings, and PowerPoint presentations. The original files retain their individual identities but are assembled into one PDF Portfolio file.
In order to view PDF Portfolios please install Adobe Reader. http://get.adobe.com/reader/
PDF Portfolios also require Adobe Flash. http://get.adobe.com/flashplayer/otherversions/
Your browser may also require additional configuration. It may require you to disable viewing PDFs in the browser. http://helpx.adobe.com/acrobat/using/display-pdf-browser-acrobat-xi.html
