Can't open CFAI Mock from website?

I keep getting a PDF error when clicking on the exams here Error message from Acrobat says the file is either not a supported file type or the file has been damaged. The file is a PDF so I don’t know why it wouldn’t be a supported file type. Anybody else having this issue with the CFAI mocks or is it just my computer?

Opens for me. Must be the version of Acrobat on your computer
