Opening PDF file disasters

  1. I am working on my dissertation and started to use some of my references previously stored as pdf files in/on my computer and pen drive backups.

    However, for every single pdf file, I now get this error message "adobe reader could not open file.pdf because it is either not a supported file type or because the file has been damaged "

    I have the following programs installed
    Adobe Digital Editions 3
    Adobe Read XI
    plus various Shockwave Players

    I have uninstalled and reinstalled the programs to no avail.

    I have checked that .acsm file extensions are set to use Adobe Reader to open with, and have also tried to set that to Adobe Digital Editions (on someones suggestion), but no luck.

    This is disaster because I religiusly save all my pdf article and research documents, but now cannot use them for no apparent reason.

    Any help would be greatly appreciated.

    Does anyone know if I can find a way to repair these pdf documents (if that is the problem)?

    1) Try opening the files on a different computer
    2) You might also try going back and install the prior release level of adobe reader

    I googled PDF repair free and saw a variety of PDF repair products with free trials. I have no personal knowledge of which are best. Hope that might help.

    /* EDIT */
    If you find stuff downloadable from CNET (or similar download sites), I suggest you go direct to the vendor's site to look at their product info and download directly from the vendor, not CNET
