Automaticaly click button

Hello guys, first i want to say i'm new in autoit scripting and sorry if my problem may be rude
I want to automaticaly click a button on a window when the window appears.

The window info is pasted below:

This is what i wrote in the .au3 file:

WinWaitActive("[CLASS:TExtMsgForm]")
ControlClick("[CLASS:TExtMsgForm]" , "" , "[CLASS:TButton ; INSTANCE:3]")

It seems that the window is detected because the script closes after window appears but no button is pressed
Also i want to run the script until i will press a key combination such alt+ctrl+x an not to close himself after detecting the window.
I must say that i run the script by double clicking the .au3 file and not by compiling the .au3 to exe and than running the exe , i don't know if this could be a problem.
Thanks in advance
