Cannot open a PDF download from a subscription newspaper
I wrote several months ago but, since then, nothing has improved. I have a subscription to our city's newspaper which allows me online access and the ability to download articles via PDF. The download appears to take place but will not open. I have tried multiple browsers and it will not work in any of them. I have even tried other readers and still the articles will not open. I have tried all of Acrobat's update info and have the latest versions. The browsers are also the latest updates. I have contacted the newspaper and their response is that they're using the same process I am and the articles open for them. I do have to login to the newspaper but mostly I stay logged in. I empty the cache. The oddity is it used to work and, on rare occasions, it works but generally it does not. I should mention that I can open any other PDFs sent to me with Acrobat. I do have a need for this to work so wondered if anyone has advice.
Here is the error message.
