Hi Albert, Today I burned your bootloader (the one with autostart) and it was impossible to install the Microchip custom driver in automatic mode on Vista Basic. It was a weird behavior - device disconnecting/ reconnecting at some intervals! I had to do it manual.
But now is working nice on my board. I did a blink test and now I will test with usb-cdc driver.
