Couldn't open PDF: something is keeping the PDF from loading

Hello!

I am trying to get some help to fix the above error message I keep getting when I try to open microfilmed newspapers on the Fulton NY Historical Newspapers site. (fultonhistory.com) and also when I click and try to load our church bulletin. It looks like the article or bulletin is loading but then you get the above error message. Hope someone can help me with this issue. I have tried to right click to see if there is an option to tell it to open with Adobe Reader but there isn't an option for that. I did update the reader to the latest version too. Up until about a week ago I had not problems looking at the results of my search but not I do. Please help! Thank you!
