Autoit script problem with bitdefender 8

[Nucleus]

Theoretically, the script is working. The problem is that when it gets to the second window, and has to enter the serial number, for some reason, after it enters the first 2 numbers, that window becomes inactive, and so the script cannot continue entering the serial number. Is there a workaround for this kind of problem?

This is the autoit script i'm using.

Run  ( @ProgramFilesDir & "\Softwin\BitDefender8\bdmcon.exe" )

WinWaitActive ( "BitDefender 8 Professional Plus - Evaluation" )
Send  ( "{ENTER}")

WinWaitActive ( "BitDefender 8 Professional Plus - Registration" )
Send  ( "xxxxxxxxxxxxxxxx" )
Send  ( "{ENTER}" )

WinWaitActive ( "Online Registration" )
Send  ( "{ALTDOWN}{F4}{ALTUP}" )

WinWaitActive ( "Online Registration" )
Send  ( "{ENTER}" )

EXIT

And this is the screenshot, after it has entered the first 2 numbers of the registration serial, but stoppped, because for a second there, the window became inactive.

ripped code from the main script in the autoit thread...should ideally fix the problem.

You can find the corrected version here [link]
