Video and audio desynch in NFS Run

I just installed NFS RUN LE in my system.
It runs smooth and i get 40+ fps but the problem is that there is a lag in video and audio. first the person says and then the video plays. I mean the audio goes ahead and video is lagging behind, and same is with subtitles, subtitles come after the dialogue, is there any fix for it?
P.S i can't reinstall game because i deleted the downloaded installer of game.

Any help would be much appreciated!

Tried Google but no result yet..
Any one else having that prob?

i have not patched the game, is there any patch available??
