Would anybody have any suggestions to fixing it? I'm on a Window 7, 64 bit operating system and I get the following error message when I try to load the server program: "Error message: This application has failed to start because MSVCR80.dll was not found. Re-installing the application might fix the problem." Thanks, Zola
