Help cr@ck DDtank tool

As you know, the Vietnamese aimbot (I am Vietnamese too) at [Only registered and activated users can see links. Click Here To Register...] is very good, but if want to use it, you have to pay some money.
That tool write in Java, nothing perfect, so we are able to Cr@ck it
----
First we need a Java decompiler, I am using [Only registered and activated users can see links. Click Here To Register...]

Open file "run.bat" I see java -cp data/wrapper/quan-util-core.jar qj.util.Wrapper qj.game.gunny.ClientHostMain

qj.game.gunny.ClientHostMain that what I care, I run Java decompiler and open: *\data\lib\client.jar and found qj.game.gunny scroll down and see ClientHostMain modify some code and done...but I don't know modify what.

I am start to learn Java and don't know much about it so, I can't cr@ck it (for now, I am 14) but I thing I am going on a "right direction".
