"itunes has stopped working" after connecting ipad mini to computer Windows 7

itunes can play 2 out of 10 movies already on my computer. Otherwise, when I start to play the other movies, I get the notice itunes has stopped working etc.

Quicktime Player VERSION 7.7.4 can get to the Apple Store and order a movie. But when I insert my Ipad mini, itunes IMMEDIATELY "itunes has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."

I reinstalled lastest itunes 11.1.3 after uninstalling it, and placed it not on the C Drive, which is pretty full but on another drive. I use ImTooiTransferPlatinum to put muisc onto my ipad mini, not itunes.
