LivePreview is not working – it displays an error message stating This view has crashed!
This issue has been specifically observed in Windows 8. You may see an error message as shown here, and no HTML will be rendered when you type in the Markdown Editor pane.
To fix this issue, please try installing the Awesomium 1.6.6 SDK.
