I recently upgraded to multisim 10. I opened a multisim 9 project and made changes to the design. No matter if i save the design or the project, when I come back the next day none of my changes are saved - it always opens to the original design. how come?
Can you attach the file in question?... (in a zip file), so we can try it, are you using hierarchical blocks or subcircuits that are still referenced to a v9 file?
