hello malcolm

I had problems also when I first tried the download. You must use the new flash upload to upload your unit before you do antthing else or all is a for nothing. I found I had to install new to make it work.
Check your SW version with the display button. The fetch will happen when you start the config program. I am using the RS232 connection.
Hope this helps.
