New Autoit = tt6 error

I have just updated to the latest autoit but the latest version give me an error when i try to run a couple of my scripts.
I am not so great with scripting and i do not understand the problem but if you could help me fix the problem i would be very grateful :handsdown:

"Picture Attached at bottom"

"EDIT"
The problem is when my script is trying to do ::

Code:

resign()
resign()
RandomSleep(4000, 7000)
MouseSend("left", "click", 403, 303)

"EDIT2"
I think i solved it with a little help from some others ;)

Changed This::

Code:

	;define missing constans
	$MK_LBUTTON       =  0x0001
	$WM_LBUTTONDOWN   =  0x0201
	;$WM_LBUTTONUP     =  0x0202 -> defined in WindowsConstants.au3
	$WM_LBUTTONDBLCLK =  0x0203
	$MK_RBUTTON       =  0x0002
	$WM_RBUTTONDOWN   =  0x0204
	$WM_RBUTTONUP     =  0x0205
	$WM_RBUTTONDBLCLK =  0x0206
	;$WM_MOUSEMOVE     =  0x0200 -> defined in WindowsConstants.au3

To This::
