Colorize license is per machine. If you want to have it on two or more machines you'll need the appropriate number of licenses.
We have license transfer cycle in that case. First you need to uninstall Colorize tool. Then send us message at our support and we'll pick it from there.
You will see this message if you activated Colorize on a new/pre-installed machine and your key was not released (you didn't uninstall and contact our support to free your key). Please write back to us with your purchase information.
If you have firewall or proxy server and you try to activate Colorize then your activation requests will fail. Try to deactivate your firewall for the activation process and then turn it back on.
