What should I do if I always got the “Invalid license key” error when registering?

Firstly, could you please confirm all characters are included when you are copying the license key to register? If it still not works, could you please use the license key to register the correct version. If you use license key for old versions to register a new version, you will get this error. Otherwise, please confirm there is no extra space before the first character and after the last character. If you still cannot activate the program, please contact our support team support@soouya.com. We will get back to you as soon as possible.
