Hi ,
When you say you cannot open IBM SPSS Statistics data files (*.sav), what is your expectation? For example, the "File -> Open" menus in Amos refer to the Amos path diagram file (*.amw). You would not use this menu to open a data file directly. The Amos path diagram file will hold a reference to your external data, not the data itself. Use the "File -> Data" menu and dialog to associate your data file with you active Amos path diagram.
I hope this helps,
