I am stuck on the "Build Your City" screen! Why do I have to start new?
This typically happens if your browser did not load the Flash Player Plugin, which is needed to start Forge of Empires.
Often this can be resolved by clicking the 'Build Your City' button, and then clicking 'Allow' in the small popup that asks you to allow Flash. Then your city should load normally.
If this does not resolve the problem, please make sure you have added an exception for the game page (URL) you're trying to access in your browser's settings. You will need to add an exception for each world that you play on.
