Sorry, you may either be using an old browser that does not support Java, or your Java support may be disabled.Be sure your computer is running at least Netscape 4.6 and above, or Internet Explorer 4.x and above. If you are running new versions of Netscape or Internet Explorer, and ICQ Lite still does not launch, make sure you have Java turned on.If you don't have the required browser version or Java support installed, you can obtain them from the following sites:
For the newest Netscape software go to: www.netscape.com
For the newest Microsoft software go to: windowsupdate.microsoft.com
For the newest Macintosh Runtime for Java go to: www.apple.com/java/

hvad kan jeg gøre ??
