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

It is due to one of these things:

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