Query: I can't froth my milk without it

I'm a beginner in the espresso machines's world and I was just frothing the milk without knowing that it needs to be done in a specific temperature, so, basically, my cappuccino was COLD and tasted very bad, so, from the time that it had been received to me, I never stopped making great cappuccino and latte as well, even when I got a new espresso machine (DeLonghi ESAM 4400 (Perfect 5 stars machine)), I continue to use it daily.Buy it, you won't regret it.Thanks,
