When I travel to Beregost my game always shut down, but when I travel to other place it works normally. First it wokrs fine, but after some 7 hour of game i can't get there becuase my game always shut down and program do not responding . I tried to reinstal game but that same problem.

Are you using TuTu?
This is a known problem and I think it's TuTu related. There is a fix however - http://www.shsforums.net/topic/24121-release-beregost-crash-fixer/

The link Petrus gave you will repair your save. I would recommend doing so, and then applying a tweak to prevent the problem from occurring ever again.
