MKII Update Error Message.

[Mixpower]

Hello,

I used Navcoder to program new languages into the MKII.
So Navcoder send the command and the MKII wants a software cd so i inserted it and got the screen that it was going to update.
But after that i got an message saying "Error occurred during programming" So i tried again still no luck i tried other firmware versions, V.22, V.25, V.30, V.32.. all no luck and the same result!
Also tried to send the command with Navcoder again but still the same message, when i use firmware V.17 i only get a Black screen and the MKII is blinking.
Couldn't find much about this problem, so that's why i'm asking here,
Does anyone know what the problem could be or how to fix it ?

Thanks!
