If I use US modules version 9 then I have to substitute all library parts (that will turn into dots on version 10) to its corresponding parts on 10?
This is a lot of work...
I think there is an Archicad 9 library subset available for Archicad 10. You should get it and load it with your libraries. Then it should work, you would keep using AC9 library parts in AC10.
