Hi
thank you for the update. finally i got a mail.
but there is an another situation i am facing now, where in it shows “Unfortunately, the automatic insertion of your activation code failed”.
manually i am not able to active, it says cannot insert license.
Is there any customer support where i can talk to them?
Could you please help me out from this.
