Version 11 keeps freezing

Hello,

I have just installed the version 11 of TestComplete and I am experiencing TestComplete freezes while its waiting for an application to run or exit.

For example, TestComplete is hanging while processing the following VBS routine : 

Do While sys.WaitProcess("SQLCMD").Exists

    Timeout = Timeout +1

    call aqUtils.Delay(10000, "Attente restauration base de données")

    if TimeOut = 70 then

      Call log.Error("Le processus SQLCMD a atteint un Timeout, il va être tué")

      sys.Process("SQLCMD").Terminate

      Exit Do

    end if

  Loop

The SQLCMD exit without error but, sometime, testComplete is hanging. Its progress bar is freezed while processing aqUtils.Delay(...)

Then I need to kill TestComplete process. 

This VBS routine did not cause any problem while I was using the TestComplete version 10.

My system is a Window server 2008 R2. I have already opened a support ticket (Case #00137385)

Any help would be much appreciated. Thanks !
