You probably miss some sleep times between your Leftclicks. Another thing would be to use WinWait("Perfect World International: Eclipse") after WinActivate. That way you're waiting till the window is actually activated.
If you want to use the method of sending packages then i put a test code together which does your DailySign here:
#include <NomadMemory.au3>
HotKeySet("{DELETE}", "_exit")
HotKeySet("{F1}", "SignIn")
func SignIn()
$pid = ProcessExists('elementclient.exe')
_DailySign($pid)
EndFunc
Func _DailySign($pid)
$packet = '9C00'
sendPacket($packet, 2, $pid)
EndFunc ;==>_DailySign
Func _Exit()
Exit
EndFunc ;==>_Exit
While 1
Sleep(10)
WEnd
Func _FloatToHex($floatval)
$sF = DllStructCreate("float")
$sB = DllStructCreate("ptr", DllStructGetPtr($sF))
If $floatval = "" Then Exit
DllStructSetData($sF, 1, $floatval)
$return = DllStructGetData($sB, 1)
Return $return
EndFunc ;==>_FloatToHex
Func _Hex($VALUE, $SIZE = 8, $TYPE = "int")
Local $tmp1, $tmp2, $i
If ($TYPE = "int") Then
$tmp1 = StringRight("000000000" & Hex($VALUE), $SIZE)
ElseIf ($TYPE = "float") Then
$tmp1 = StringRight("000000000" & _FloatToHex($VALUE), $SIZE)
EndIf
For $i = 0 To StringLen($tmp1) / 2 - 1
$tmp2 = $tmp2 & StringMid($tmp1, StringLen($tmp1) - 1 - 2 * $i, 2)

With this you can do your Sign in via F1 and close the program again with the delete key :)
A completely different way would be to use ImageSearch to find the buttons, that way it would work basically always.
