    JeanineB007,

    Let's start with some info. Your post appears in the tech community for Microsoft Project. Is that the application you are using? If so, what version is it?

    What exactly are you trying to do with your macro? Did it work okay before? A snippet of your macro code showing where it attempts to open the Project file would help.
