You won't be able to update any of the old mudclient bots because Jagex have upped RSC's detection system and now record mouse clicks.
So when you are on the official client it send the location of the mouse pointer when you equip an item or attack something and of course it is correct. When you are switching items, prayers or attack styles on the bot the packet gets sent but the mouse location is wrong, so you'll get banned.
There's one RSC bot out there at the moment (but it's probably unsafe, and if it isn't now it will be at some point.) that gets around this and of course colour clickers do too. Mudclient bots are pretty much dead, BCEL is the way forward.
Oh, and it's not hard to switch items when staking and PID has now been randomized so staking bots are kinda pointless IMO.
