Update Flash and Java to the latest version.
Download and install the latest version of both programs.
Flash and Java are important to the core functionality of many websites and games.
Keeping them up to date is very important for the best gaming experience.
Make sure your Firewall is not blocking connectivity
Each copy of Windows XP and Vista come with a built in software firewall. Sometimes these firewalls can interfere with the connection to the game.
In many cases adding your browser as an exception to the approved programs and services will solve connectivity issues.
In other cases you may have to reset your software firewall to the factory defaults.
Also keep in mind that most routers also function as firewalls. If this is the case you may want to even consider disabling your software firewall.
Lastly, please check your Antivirus Suite. You may not realize it, but you may also have a firewall installed there, in addition to your Windows Firewall and router. Many people unintentionally double or triple firewall their computers, which can unfortunately result in a loss of connectivity to the game servers.
Make sure your operating system files are up to date.
