Hi Chris,
I'm sorry that you're having trouble with Reader. Adobe Reader is free, so I'm guessing that what you purchased was a subscription to one of the Acrobat online services (PDF Pack, ExportPDF, and so on). But that shouldn't have any bearing on the issue that you report.
Are you able to open any PDF files in Reader? Do you receive an error message when you try to open the one you reference in your post?
I look forward to hearing back from you.
Best,
Sara
