Something here doesn't make sense. I don't get it - how did the light come on even though the fan did not come on? (This is assuming that jcarrejo installed the fan at the spot of an existing overhead ceiling light, and wired both the fan motor and the fan's light kit into the existing ceiling light wiring.)
Are you sure you didn't just somehow short out/mess up the fan motor only? You mentioned that you realized that there was "no power in the room." Are you saying that you checked all of the outlets in the room with a known working plug-in device like a light, fan, radio (does anyone even have these anymore?) to see if there was still power to the room's outlets?
This is assuming that your daughter's room's outlets are on the same circuit as her original ceiling light fixture. (However that is not always the case because I have one room in my house where the ceiling can lights and outlets are on a different circuit than the overhead fan.)
Like yodaman said, you should double-check the breakers, but I still don't understand how the fan light would come on but not the fan motor if you wired them to the single pair of black and white wires in the ceiling.
BTW, you "should" know which breaker controls the ceiling wiring because you should have turned it off before attempting to install the fan, right? (i.e., no real need to turn off and turn on all of the breakers, except as a last-resort wild guess)
Don't take any personal offense but if you didn't originally turn off the breaker before working on the fan and trying to wire it in, consider yourself darn lucky to have gotten this far without getting shocked!
