Can't open certain PDF files. Getting a corrupt error.

Adobe Reader could not open 'hourly.pdf' because it is either not a supported file type or because the file has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded).

I was able to open them a few months ago, but at some point (not exactly which date), I just started getting this message on only some of the pdf files from different folders on my network drive. These pdf files were originally e-mailed to me way back when, and unfortunately I don't have them retained in email server.

I tried opening in FireFox, Adobe Reader 9, 8, and 7 and still no luck.

Try a non-Adobe PDF reader (e.g. the FoxIt Reader - or NitroPDF - To run a quick test, just get the free eval versions they offer.

Chances are that your PDF files are corrupt. Maybe because of disk problems, network problems, virus related problems or other reasons. If they are corrupt, it is possible that a non-Adobe product can extract more data than the Adobe solution (even though it's not likely).
