Reply to Kontrol X1 with ableton - simple mapping problem

Hi,
what on earth is happening?
I mapped, from kontrol x1, one single button in ableton to play one single mp3 file.
Everything is fine on first press of the button.

The problem is:
When i press again the button i expect to play the track from the beggining instantly.
This is not happening at all because the little icon play button from ableton first is blinking 3 -4 times ,so only after 2-3 seconds it starts playing the track.

I`m running ableton 8.2.6 Demo version (yesterday downloaded from official website)

PS Sorry for my english and thank you in advance
