afk bot problem

i have an afk bot and it works perfect for me. it already got me 50%. but my friend when he tries to play with it his combat arms gets shutdown. if its patched how come i can play with it

well its different well his acount could be like banned or something or he has hacked before or its just thats pached for him its same thing like some people cnat use some hacks but some can it just dependes even the type of computer

well its not the account thing because we share the same account but it might be because of the computer
