Yes, I can.  You are trying to open a file name with a tab character in
it.  That is, your file name is C colon tab E S T dot M P P.

    a.FileOpen( "C:\\test.mpp" )
    a.FileOpen( "C:/test.mpp" )

That's the online help.  Project is just telling you where you could
look for more information about the error message.
