To change your licensed domain name:
1) Login to your client area at centova.com.
2) Click Manage Product Licenses and select your Centova Cast license.
3) Click the Re-issue license key link. (See the section below if you do not see a Re-issue license key link.)
This will authorize the reissuance request on our end. Next, you just need to tell Centova Cast to request a new license. Login to your server via SSH and run:
rm -f /usr/local/centovacast/etc/license/license.key /usr/local/centovacast/centovacast restart
The license change will take effect immediately.
