Why won't winactivate work?

[Zamp]

This is my script

#include <Misc.au3>

$dll = DllOpen("user32.dll")

While 1
    Sleep (100)
    If _IsPressed("77", $dll) Then
        WinActivate("AC Tool 5.4.0 - C:\Program Files\AC Tool\MS - Bot.mac")
;MouseClick("left", 664, 520)
        ExitLoop
    EndIf
WEnd
DllClose($dll)

I run the script, press F8, but nothing happens. I made sure that I have the right title for the window, but it still doesn't work.

Edit: I just tried it on Firefox, and it works, but it doesn't work for the program I need it to work with. I've used the AutoIt v3 Active Window program to get the title of the program, and it still doesn't work.

What does FireFox have to do with anything? Run this and then fix the bug in your WinActivate call:

#include <Misc.au3>

$dll = DllOpen("user32.dll")

While 1
  Sleep (100)
  If _IsPressed("77", $dll) Then
    MsgBox(0, "Status", "You pressed the F8 key")
    ExitLoop
  EndIf
WEnd
DllClose($dll)
