In order to be able to use the Instant Challenger, Java and Java Script must be installed and activated. We recommend to use the official Sun Java 2 Runtime Environment (J2RE), available for Windows, Linux, Macintosh, Solaris and other major operating systems. If the Chat in the Pre-Match window does not appear, then Java Virtual Machine is not installed on your system, and/or not correctly configured.
- Internet Explorer - if applet does not load, download and install the Sun Java Plug-in.
- Netscape/Mozilla - download and install the latest version of the Sun Java Plug-in.
- Opera - make sure you installed Opera with Java (available from the Opera Webseite).
Java must be installed only once, no further programmes are necessary.
