Error code 4 when running example code

[LaOrhyUAcMji]

I used the following code:

#include-once
#include <MsgBoxConstants.au3>
#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <ThorstenWillertMultiInput.au3>

Global $aTexts[5] = ["**Verzeichnis**", "Benutzer", "Passwort", "", "__Information__"]
Global $aInputSt[5] = [-1, -1, 32] ; $ES_PASSWORD = 32

Global $sValues = _MultiInput($aTexts, "Test", $aInputSt)
If Not @error Then MsgBox(0, "", $sValues)

ConsoleWrite("ERROR CODE: " & @error & @CRLF)

Console Output:

"C:\Program Files (x86)\AutoIt3\SciTE..\autoit3.exe" /ErrorStdOut "C:\testmultiinput.au3"
ERROR CODE: 4
Exit code: 0 Time: 0.04706
