Problem opening some PDF files in Adobe Reader X & XI
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.
