I uploaded my first program to ATmega328p and now i cannot upload anything
Ok, it seems I solved it out. I feel really dumb but I gotta say what I did for other dummies with the same issue :)

I added the quartz and burnt another bootloader (eventually it was duemilanove 328) and then I just did File > Upload using programmator (im not sure of the english translation) and it worked... I didn't even know there is diffrence between upload button and this.
