Files might be corrupted, The printer Friendly doc, as well as default version downloads a PDF with blank pages for me
I'll keep investigating on this one. Thanks for letting me know and sorry for the issue! My only initial thought (since I've had this issue with other pdfs in the past, personally) is you may want to make sure the program is as up to date as possible. If you grab the free Adobe Acrobat Reader or open it in a browser like Chrome, that should work in the meantime.
