manee I'm sorry to hear that you are unable to activate Spine. Based on the error message you shared, the second activation may not have been successful due to an internet connection issue. I checked the status of the license associated with your email address and found that everything looks normal. You should be able to activate it as long as you can connect to our license server.
Unfortunately, we do not have servers in China, so access from China tends to fail. You may need to try multiple times, try again later, or use a VPN.
