Kigen's Anti-Cheat

Hey.. i play CS:S a lot, and my friend gave me this lua script, (he uses it all the time and nothing has happened to me) I don't really know how it works.. but you type menu_open into console, and it opens up a menu which you can then use your arrow keys and choose what you want to do.. eg- retry all, disconnect all, block FCvar, Mute mics.. etc
I tried it on a server.. Then got KAC banned.
I am hoping to get unbanned
I also deleted the script and i just want to play normally D:
