Hi @lubos, thank you for that info. So we no longer have any idea what version we happen to be running at any time, and whether or not we need to update.
You will need to update the other computers to near the same version before opening Manager files on them otherwise data issues will arise e.g. the latest version now uses proper names for the business data files, the previous versions used cryptic names, so the older version wont be able to recognise the proper name files.
