First of all we apologize for the delay in assisting you in the past. We have just undergone a major personnel change and have instead prepared a new plan to support better development to deliver a better quality service to all of our customers.

From May 1, 2021, we will migrate to the customer support and management system on the new platform. You can submit a support request, come up with ideas for a custom request if you want. All in one platform. We always acknowledge all of your comments.

You can register your customer account here with your purchase code:

Or you also possible register new account as a customer without purchase code

Again apologize for the delay in the past time. We're back for a better service mission.
