External BoxEsp Problems

Firstly, i used the 4.32 sniper aimbot i launch it but it doesn't when i reopen it says externalBoxesp is already running. But when i open mw2 the hack doesn't work i just get the normal mw2 i have tried it no full screen as well as windowed. I have aeroo theme running. I also tried running mw2 then al+tab out and launch the hack but still doesn't work. I use the standalone .exe.

Secondly, with 5.1 externalBoxesp works perfectly except the aimbot. i pressed home as well as home and right click togather to try and change the aimbot speed. But after pressing it nothing seems to appear that tells me the aimbot speed.Aimbot also doesn't aim and yes i have turned the aimbot on (f5) lol.

Can anyone tell me any suggestions or any way to fix this?

thanks
