Hi,
I'll describe how I updated my firmware -I hope it cures your problem.
You will need an rs232 female to female null modem cable.If your computer does not have an rs232 port you will also need a usb to rs232 converter.Both are available from Maplin or maybe Amazon.Install the usb to rs232 converter on your computer.
Goto _http://www.fortecstar.com click on downloads and select the model of your stb.Download the latest update for your stb together with loader v1.5.
Download a copy of the Fortec Star rs232 tool (FS download manager) and FS download manager procedure ( both available on this site)
When all files are unzipped they will have .dnl extensions.
Connect the stb to your computer using the null modem cable and usb/rs232 adapter if necessary.Switch off the stb.
Run the Download Manager and select port number,baud rate (say 9600) and Loader V1.5. (See Download Manager Procedure).
Click on 'dowwnload' and switch on the stb.
When the loader update is complete run the Download Manager again to update the firmware you downloaded from _http://www.fortecstar.com
I hope this works for you. Good luck.
Mike M
