These error messages come up:

PDF error

/Users/PaulDeridder/Downloads/9.0 section I FDA 3674 UCM048364.pdf could not be opened, because an unknown error occurred.

Try saving to disk first and then opening the file.


WORD document

Adobe Reader could not open '7.1.2.1 Wuxi Cold Genesys CG0070 Stability Protocol.doc' 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).
