# Note

  • Your emails will be replied within two working days.
  • Sometimes, you cannot get technical support or get your license key by email.
    If you encounter such a situation, please don't worry. There is only ONE reason this will happen:
    We cannot receive your emails or you cannot receive our emails (spammed or rejected).
    So, if you encounter such embarrassment, please don't hesitate to request support by using other email addresses until you get it.
    Although this probability is small, but you still have to pay more attention about this situation.
