This is a very simple issue to fix. You have not configured your 'Core' package, which is for your local forecast. You need to configure the 'Current Conditions' Site, your 8 Local Observation sites, and Extended Forecast City. Once you have configured all of these, then when you 'Review Cfg'n' There will be a link at the bottom of that page that will appear as: 'Build any settings into active cfg'n: Build Now!' .. Once this has been completed, the emulator will no longer complain that the ID no longer exists.
Try that and see if you have any more problems. Thank you!
