after a few tests this is what i have to report,maybe you could solve the problems:
1)fast attack quits the game giving an unknown error (?????? signs and ok button)
2)mobber quits the game in the same way as fast attack
3)autopickup quits the game when you try to sort the items to pick up,but if you stop item sorter and pick up everything it works ok
4)attack speed does nothing,not increasing attack speed nor slowing it down
5)speed hack instantly quits game or sometimes exists with "program stopped working" error
the only working hacks are autopot,metin detector,autoattack,range pickup(all items),wall hack,experience donator and teleporter
