I mighy add that I called today that company when the LED that indicates that a prog is loading wasn't reponding at all and the prog on the pc used for download gave error message as well, and that guy advised me to download a prog called " user port".
Thay prog apparentlu enables the parallel port which is used by my board.
So when I installed tthis prog the LED was suddenly responding and the error message wasn't comming anymore as well.
But still the MC seems not to be working proberly.
