Could anyone tell me how i can use livesplit with SMW, because i am new to this and i need help hooking it up with the game.

When using Livesplit to time your SMW runs, you don't need to hook it up to the game.

You simply use it to start and stop a time-watch. Right-click and check the "settings" menu to view and change your hotkeys. I understand if my answer isn't good enough, but your request feels a bit vague. What exactly do you want Livesplit to do?
