Hi,

I downloaded .pdf file from Internet and it displays perfectly in the browser.

However, if I save the PDF file to their computer, the downloaded file becomes corrupt. The PDF file is always some KB, but very important to me.

The error message when I'm opening the downloaded PDF: error at opening document. and file is damaged
