I paid 3 days ago; but I cannot reach the cwp billing team. Even though I paid, my licenses are pending. I'm waiting for a response from the authorities.
Is your correct IP showing in your account for the CWP Pro license? Try temporarily disabling your firewall and then run CWP update.
You can check in terminal:
curl "http://www.centos-webpanel.com/ip/"
Then run this to activate it
sh /scripts/update_cwp
disable firewall
Enjoy!
