I tried to register at the C&C Online website, which failed with a 502 error. My account seemed to be created anyway but I never got the activation mail.
Then I tried to resend my activation mail which failed aswell with a 500 error.
After changing my email around I got an activation mail which succeeded this time. But unfortunately my C&C Online account is still not activated.
When I login on C&C Online I get:
"This account has not been activated yet. Please follow the activation link sent to you by e-mail."
