Thnx for the reply!
Sadly, Acrobat gives me the error message: "Acrobat could not open xxxxx.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)".
When I try to open the file in MS Word it wants me to convert to another encoding. IE and Firefox just give me a blank screen, just like Chrome.
