Download the DarkShield bypass or xivison bypass latest version .
If S4 league dosent appear , wait it 2-4 minutes . Check it at task manager , if the memory increase 130k and stopped for 1 min , just wait for it . 2-3 min later the memory increase to 1m then S4 League will appear . Don't worry dude .
If it still crash , run it as admin . Btw where do you extract it ?
