Hello
The new CodeWarrior for HC08 (V5.x and higher) are not using stationeries any more to create projects, but a wizard.
You should still be able to program the Nitron (QT) board with these release.
Either use the wizard to create a project for HC08QTx or in the startup screen you can select "Load Example Project" and select a HC08QTx project from there.
A new project (duplicated from the selected demo project will be created and should be set up for the board.
I hope this helps.
