I've heard of the Flash storage getting corrupted somehow. Try this:
Go to the Single or Multi-player tab (it’s okay if the app doesn’t load), right-click and select “Global Settings.” Then click “Local Storage Settings by Site” and delete any entries that mention warlight – there should be a “gae.warlight.net” and there also might be a “warlight.net”
You can also try going to [this link](http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager07.html
) and deleting the entries for WarLight.
