NumConvertBase UDF

[The_Noob]

I have a problem... I have my code below:

#include <NumBaseConvert.au3>

$num = '44e15d91c5abe7f62add55bd052401'
$new = "" 
For $i = 1 To 15 
    $new = stringLeft($num, 2) & $new
    $num = stringtrimleft($num, 2)
Next

$twentyfour = _NumBaseConvert($new, 16, 24)


MsgBox(0, 'Start: ' & $new,  'Number in 24: ' & $twentyfour & @LF & _
                             'Number in 16: ' & $new)
                             
                            ;$twentyfour should return 
                            ;4adm6li41hbah7h1mh569fhak

the base 24 that i should get back is "4adm6li41hbah7h1mh569fhak", but thats not happening. Is there a way to make your prog work better with long (30 char) strings?
