AutoCoast problem

Hi everyone, has somebody found a way to "clean" GSHHS data? This data, which is pretty accurate, seems to have few points here and there that are way off and causes FS to chrash (I think). The results that I got using this data with AutoCoast was amasing. The program just spat out the whole coastline of my country whith all Islands and lakes using one command line. I was disappointed when after few minutes of flying, FS crashed. In some areas one can fly for few minutes in other FS crashes instantly.thrimur
