Morning, the license verification window should only show when you start the cBot for trading, it should only display once when you start a backtest or optimisation, are you seeing multiple popup windows that crash your trading platform?
If optimisation stops then your settings are incorrect, can you export your cBot settings as a text file and use the upload button to post it here, can you also share a screenshot of the cBot log?
To save your cBot settings just right-click your mouse on the cBot instance in cTrader automate and choose save.
