ConfigManager Error in Application Builder

I am a new user to the ArcGIS Viewer for Flex - Application Builder, Version 3.4. I have been encountering an error message when working through the Builder. I have no issues when I use the first 3 tabs of the Builder, but when I move to the "Design" or "Preview" tabs, I end up with error messages. The first message reads, "Fault code: InvokeFailed; Fault Info: Error #2148; Fault details: null" The second message reads, "Some error occurred. ExternalInterface doesn't work in Standalone player."

Can anyone point me in the right direction?
