First Time Hacking Help Me Please. :(

So I am new at hacking...but I followed all of the instructions on how to apply the hack to crossfire.Well I get up to where you choose a server and it detect the hack.I already got banned on two of my CF accounts.What do I do wrong?

maybe you use detected hacks ?

No.I am using Assasain Creed V4...he just put it up a few hours ago.But Idk...maybe that is the case.
