the 1.43 ver is already out, it helps set the correct aimbot sensitivity.
I got no idea why the aimbot crashes on the start for some people while it works for others. The aimbot works on my vista 32bit desktop computer AND 64bit windows 7 laptop computer. So until I can reproduce the error or get an idea what the error msg is then there is not much I can do. Do you have framework 2.0, 3.5, and 3.5 sp1 installed?
