The code worked before, but now it doesnt, whats wrong?

while (true) {

if (GetAsyncKeyState(VK_F1) & 1) {
granade = !granade;
cout << endl << "GranadeHack " << (granade ? "включен" : "выключен") << endl;
cout << granade << endl;
}
if (granade && (GetAsyncKeyState(0x43) & 1)) {
granade++;
GranadeHack();
}
if (granade) {
GranadeHack();
}

}

return 0;
}
