Problem opening some PDF files in Adobe Reader X & XI

[Steefan]

I have several PDF files that cannot be open in neither Adobe Reader X nor XI, in Win7 64-bit as well as Windows Server 2008 R2.  I have the message as shown below:

There was an error opening this document. The file is damaged and could not be repaired.

BUT the files are NOT damaged because I can open them with another software called XChange PDF Viewer.

Where can I file a bug to Adobe so they can fix the bug?

Thanks in advance.

This often happens if people save files from Safari, on the Mac, the wrong way. It's a sad but true fact that several ways to save PDF files from Safari seem to work but actually save some old junk instead of what you actually want.

The only safe way to do it is to hover over the PDF until Adobe Reader's toolbar appears, and then to click the Save icon.
