OK, it seems to have imported everything in my database, but all the text fields contain a string of the form: "TechnicalName.field"
So when I use an ArticyRef picker, the window is full of icons all labelled Dlg_XXXXXXXX.DisplayName or DFr_XXXXXXXX.Text, rather than showing the string contents of the variable.
These strings are the same if I browse the database in the Properties pane. Bug or user error?
...Icons and colours have imported fine though
