If you get the following error in your turnkey application:

Not able to start, check the CurrentVersion - is it set? Check that the app is Started and not Paused. Check that the Version is in DatabaseUpdated state

Then it is one of these things:

1. You have not yet uploaded a model from mdriven designer and the list of models is thus empty
2. You have no CurrentVersion set so the MDrivenServer does not have a modell to work with
3. You have you app in Paused mode - it must be started to allow normal work
