Why won't iTunes transfer any song or any file to any of my devices?

I have unistalled and reinstalled iTunes multiple times. When I go to to transfer a song to iphone, ipad, ipod it just freezes up and doesn't do anything. I'm running the newest version of the program. What do I need to do? Just want to fix it. Thanks. I have waited on the program to transfer just to see if it is slow or what and it took 30 mins and nothing. I can't download software updates also.

Maybe there's sth wrong with your iTunes. You can turn to some other apps, such as Wireless Transfer App. You can have a try.
