The update is seamless and perfect for the loco database, routes, Demand Contacts and timetables... The only thing that I had to do was to update the description and icon (lights, telex, etc) of the functions for each loco..
The only comment (not a complaint) is that the popup window that starts just affter you try to load an older database is in German and it is a little scary until you realise what is happening..
It is a great product and a worthwhile upgrade - I am very happy..
