Hi i used to play emps about 3 years ago and im guessing that is why this is happening, my slayer task is to kill "Kurasks" which require 70 slayer to kill, yet these are my first slayer task... I'm only 30 slayer and have not receieved any slayer points because i still have not completed my first task which back then i could have completed but now they require 70 slayer so i can not. Please let me know if you need any more info to help me out, simply resetting my task is all i need. Ingame name- Riptidelax12
Thank you

talk to chaeldar to reset your task for a new one, this is described in the wiki page for slayer
