>Nadya,
> I am running NT Workstation. The server has NT Server, but I Adobe installed on my machine, so I don't know how that would affect anything. I have Office97 but it installed the DLL in the Office95 directory. Could you send the pdfmon.dll to randy_belcher@yahoo.com. I will try to put it into the Office97 directory and see what happens. Thank you for your help.

Check your e-mail. Also try to check the content of your current DLL, may be it's a wrong DLL version.
