Hi, Ricardo, can you provide your order number and the version number of the product, you will see this in the window below. If you do not see the same window, download the latest update.
If you are using the version above, please share a screenshot of the message asking you to register the product again.
Can you also take a screenshot of your cBot log using cTrader automate when you start the cBot as I have..
If everything looks like above, share your cBot settings, the symbol you are using and the steps you are following to use it.
