No audio output PT 12

I installed Pro Tools and all the necessary audio drivers for my Behringer U-Phoria UM2 audio interface. After launching Pro Tools, i cant hear any output. All settings in IO is set. I can record, it shows levels and gets recorded. But cant hear anything in playback. Whenever i open Setup>Hardware, the hardware setup window opens and then Pro Tools freezes.

Dell Inspiron 1440, Windows 7 Home Premium 64 bit, Behringer U-Phoria UM2 audio interface, Pro Tools 12.
