I do not quite understand what you mean.
Maybe try to download the official Le Bot 8.4, since Le Bot 8.9 is just a ripoff version. Someone changed the version number and got some downloads and clicks off it.
If the problem still persists, please try to explain your process more in depth and I will try to help you out.
Bot command stop working..is this what u trying to say?If so it actually internet or server problems and it will fix itself around 2 or 3 hours.This happen to me a while ago
