The link should have worked until about 3 months ago when I shut down my webserver.
The attachment is the last zip I made. I doesn't include the cdafk. I'm a little surprised that nobody else has released an afk script like that.
On topic:
The afk script needs deuspack, a line to autoexec.cs after the deuspack line, and one bind.
This should be the easy way to make it work. For example in autoexec.cs:
exec("DeusRPGPack\\DeusInstall.cs");
exec("cdafk.cs");
bindCommand(keyboard0, make, "f10", TO, "ToggleAFK();");
Don't add the deuspack line if you already have one.
