Hi Al-yeti,
Thanks for the reply,
I can't see any text on the keypad, the virtual keypad or the web interface, so I don't which key presses will get me to the menu to update the file.
If someone can give me a list of key presses to try and load the file from the SD card, I can give it a try and hope that works.
something like this:
From the web
start with the spanner icon,
then choose the 4th option down,
then the 3rd option
etc.
or
from the keypad
enter installer code
enter user code
click the tick
press the down arrow twice
press the right arrow
etc.
