I know it worked in the begining but when i increased the number of players to 8 from 1 player i tried to test it and then nothing happens, that is why i posted my trigger i thought i might have overlooked something, but now is it possible my map is screwed? I will try an test map with the trigger, if it doesn't work then my Warcraft may had some error or something.

You mean this is a multiplayer rpg ?

I think there is basically nothing wrong with the cinematic itself, just how it is activated, maybe remake the conditions?

Yes it is an open RPG meaning you can play it single or multi player, as you wish.
Now i have fixed the problem it was at map initialization, i have made an custom variable player group = all players and then i read somewhere that player groups leak then i called an cutom script call DestroyForce(udg_MY_PLAYER_GROUP) which screwed my future cinematic.
