Why won't RuneScape work on my computer?

Java

There can be several causes for RuneScape not working correctly:

* Make sure you have the latest version of Java installed. * Make sure you are using a browser known to work with RuneScape, such as Firefox, internet Explorer, or Safari. * If you are trying to use RuneScape in high-detail mode, make sure you have a powerful enough video card and that the drivers are up to date or you have a firewall or security program installed on your computer

open it and disabel the firewall and Windows firewall
