Fixed Problems requesting something!

[Kari]

Hi,

Okay so somehow I ironed out all the problems. But I would like to request your KAC sourcecode and KAC .smx file so that I can try it and see if it will stop the exploit like it does so well on your guys servers.

I would really really really appreciate this as I am constantly under attack now =/

Perhaps we could even do some testing on mine/your server with certain exploits I know of.

Thanks.

[siosios]

this is the version im using, it is the stripped version posted in the KAC plugin thread.

notice in the code below it has:

RegConsoleCmd("changelevel", BlockExploit);

Have you done any editing to it?!?!

Please accept me on xfire and steam..
