      Although I have found other threads in this forum relating to this error - none of the fixes appear to work. I've not found precisely the same error number (0:521), might I need a different fix for this? Has anyone else had the same error?

       

      Just to note, this appears to be an issue with Internet Explorer 8 on Windows 7 while viewing pdfs 'in-browser' i.e. using the plugin. Other versions of IE on other machines and FF on the same machine work fine on the same pdfs. It also works if you right click the pdf, download and view it in Acrobat Reader 'locally'.

       

      Any help greatly appreciated, I'm stumped.
