IE8 NO ABRE VENTANA DEL CHAT.

Requiero la siguente ayuda. Desde que instale IE8 BETA 2, el navegador no
abre la ventana para el chat. Cuando entro en la pagina principal y le doy
clik al icono del chat volano se queda abriendo sale la siguiente leyenda:

VolanoChat Server
Unable to Connect
Problem
The VolanoChat applet failed to connect to the VolanoChat server either
because the server has reach its capacity or because the server is
temporarily down.

Solution
Wait a few minutes and try again.

If that didn't work ...
You may be trying to connection through an HTTP proxy server. The VolanoChat
applet cannot connect to the VolanoChat server through an HTTP proxy server
because it doesn't communicate using HTTP. Try switching the connection to a
SOCKS proxy server or try using a network address translating (NAT) router
for your firewall, if either of those options are available for you.
VolanoChat works fine through a firewall using SOCKS or NAT. Your network
administrator may be able to help you change your settings to work with
VolanoChat.

Eso pasa en la pagina que tiene este tipo de chat volano. He actualizado el
java. Pero nada. No se que configuracion de IE8 esta bloqueando el acceso.

Tengo instalado el nod32, spyware terminator, el zone alarm. >Hasta el
momento todo funciona bien contodas las paginas a excepcion de este
problema.

agradezco su ayuda.
