Hi
The behavior you are describing is commonplace for the "Analyze -> Amos Graphics" menu item within IBM SPSS Statistics. In later versions, that menu item has been removed.
IBM SPSS Amos is a completely independent program from IBM SPSS Statistics, not a subset of it. It can be launched independently of SPSS Statistics. It can read SPSS Statistics system files (*.sav). What it cannot do do is access the SPSS Statistics working file and then pass that working data back and forth.
Please treat Amos as its own standalone product. Associate SPSS Statistics system files with your path diagram file within Amos, as you would the other file formats Amos reads.
I hope this helps!
