Script stops (freeze) -please help, Script doesn?t process all records in _FileListToArray.

I am new in this and I really need help.
  I have this script - works fine for about 50 records and than stops (freeze). If I launch the script again, works for one or two records and then stops again. After a while I tried again. The script execute up to “Send("{CTRLDOWN}{SHIFTDOWN}f{CTRLUP}{SHIFTUP}")
“ and freeze again. It did work yesterday, but now doesn’t process all records in _FileListToArray. No error messages.
I created a script using AU3Recorder. 
  Your help will be appreciated.
  Thanks.

Here is the script:

#include <File.au3>
#Include <Array.au3>
$Folder1 = "C:\working\";<-- Fill this in correctly
$Folder2 = "c:\complete\";<-- Fill this in correctly
$Files1 = ""
$Files2 = ""
$File = ""
$FileWin = ""


$Files = _FileListToArray($Folder1)
For $i = 1 To UBound($Files)-2

$Files1 = $Folder1 & $Files[$i]
$Files2 = "c:\complete\" & StringLeft($Files[$i], StringLen($Files[$i]) - 4) & ".jpg"
$File = "c:\templates\" & StringLeft($Files[$i], 9) & ".app"
$FileWin = StringLeft($Files[$i], 9) & ".app"

ShellExecute($File, "Open")
WinWait($FileWin & " - Application","")
If Not WinActive($FileWin & " - Application","") Then WinActivate($FileWin & " - Application","")
WinWaitActive($FileWin & " - Application","")
Send("{CTRLDOWN}{SHIFTDOWN}f{CTRLUP}{SHIFTUP}")
WinWait("All Files (*.*)|*.*||","")
If Not WinActive("All Files (*.*)|*.*||","") Then WinActivate("All Files (*.*)|*.*||","")
WinWaitActive("All Files (*.*)|*.*||","")
Send($Files1)
Send("{ENTER}")
WinWait($FileWin & " - Application","")
If Not WinActive($FileWin & " - Application","") Then WinActivate($FileWin & " - Application","")
WinWaitActive($FileWin & " - Application","")
Send("{CTRLDOWN}{SHIFTDOWN}x{SHIFTUP}{CTRLUP}")
WinWait("Export file","")
If Not WinActive("Export file","") Then WinActivate("Export file","")
WinWaitActive("Export file","")
Send($Files2)
Send("{ENTER}")
WinWait("Export as JPG","")
If Not WinActive("Export as JPG","") Then WinActivate("Export as JPG","")
WinWaitActive("Export as JPG","")
Send("{ENTER}")
WinClose($FileWin & " - Application","")
FileDelete($Files1)
Next
