macro error 'ID List' could not be found

[msdd]

Hello,

I have recently changed over from system 9 to OX 10.
The following command in a macro written in system 9 has worked on the new OX 10 system before but suddenly now the ID List can not be found. The path is
/Users/durand/Desktop/Raw Data/ID List
The command is:
Workbooks.Open FileName:="Macintosh HD:Users:durandesktop:Raw Data:ID List"

Any ideas as to why the file is not seen?

Thank you,

Debbie
