.... can't activate any of the licenses
License activation is a separate process from extension store. The error message - as Rich mentioned at the previous message - definitely refers to communication problem. Either extremely slow connection or firewall is blocking the communication. Please try to whitelist our server's IP address at your firewall and try the activation again. The IP to whitelist is: 178.63.47.155
Thank you for the information.
