[SystemFail]

Hi everyone. I am new at forum and my english is not very good really, so i need help about my script. My script in .hps file is
void OnStart()
{
AddUseItemCallback("", "TheKey_1", "door_1", "UsedKeyOnDoor", true);
}

void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("door_1", false, true);
PlaySoundAtEntity("", "unlock_door", "door_1", 0, false);
RemoveItem("TheKey_1");
}



{
AddEntityCollideCallback("Player", "The_Quest_Area", "GetTheQuest", true, 1);
AddEntityCollideCallback("Player", "The_Complete_Area", "FinishTheQuest", true, 1);
}

void GetTheQuest(string &in asParent, string &in asChild, int alState)
{
AddQuest("thequest", "TheQuest");
}

void FinishTheQuest(string &in asParent, string &in asChild, int alState)
{
CompleteQuest("thequest", "TheQuest");
}
I am getting the Fatal error when i try to enter my custom story. The error is; FATAL ERROR:Could not load script file custom_stories/bla/maps/bla.hps!
