The "gracefully refresh" error means that QlikView is not able to save the application, as long as it is being used by for example, a developer that keeps it open. Make sure that you set the QMC, System, Setup, QlikView Servers, Documents tab to "Allow only one copy in memory" of the document.
Make sure as well that what you develop is a different file. And finally you might need to increase the time the file is reloaded to a, say, one minute...
Hope that helps.
