Can not copy any songs or videos from iPhone to iTunes

[vivitree]

I am experiencing trouble with my iPhone. I have to reinstalled my Windows 7 OS due to some trouble. When I reinstalled everything include iTunes back, it can not automatically back up my iPhone to iTunes like it used to. Also, I can not copy any songs and/or videos from iPhone to my iTunes.

Does anyone know how could I restore all my previous services I got before the reinstallation? Help!!
Very thanks.

You can only install stuff from your computer to iPhone not the other way around through iTunes
