# Note

  • We only accept English emails.
  • 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.
Remote Support (Fee-based)



When you cannot properly use our software products (even have read the documentations), or cannot solve the problems by yourself (even used the free email support), it's time to use our remote support service. It's a real-time and hand-to-hand service, your problems can be solved soon by our support team.
