Hi Jerome
Where did you buy your World-In-Box, If you bought it from a reputable dealer then they will upgrade it for free. I am the manager of a certain satellite shop in Paphos & we update our World-In-Boxes to our customers for free. All the customers have to do is call us & we will let them know that we have the latest software & then they just bring them in and it takes 5 minutes.
alternatively visit the following site
www.starsw.com and download the software that pertains to your box. You will need a RS232C cable configured as below
2 to 3
5 to 5
3 to 2
when you have downloaded the program unzip it
Connect this to your computer & digibox (make sure there is no power going to the digibox) run the arioner.exe program. open the unzipped file that you wish to upgrade. then press the send program to ird, you will receive a message stating "waiting to connect request ack" now power on your digibox & it will start sending the data packet. when finished it will give you a message stating download success. Now reconnect your digibox to the dish & put the tv on to the channel that you wish to upgrade i.e. multivisi0n and wait. it will give you a message stating upgrading and eventually it will come on.
hope this is of some help
