crash error

I've noticed every time I play nscripter engine games after a while in the game at a certain line/ point the game says there's an error and if I press x or ok it crashes. this has happened to me in 3 different games all of them were nscripter games, also the top that should show full screen...

I wonder who's fault that when I try play Sengoku Hime 4 it's get crased in the begining game it say the game engine error :( Its because there a problem when I try to instal it or the problem is from the source download can someone help me please
