My Uno suddenly stopped working(solved, someone's stupid)

[deaddoe]

Here's a code:

int led = 2;
void setup() {                
  pinMode(led, OUTPUT);     
}
void loop() {
  digitalWrite(led, HIGH);   
  delay(1000);              
  digitalWrite(led, LOW);   
  delay(1000);               
}

Circuit is pretty simple, so I'll just include a photo:

It doesn't show any error codes, it simply does not work.
