Hi, This is not a license issue, but an issue with your cBot parameter settings, the title of the popup box is misleading. Just set the Single Trade/Account parameter setting to NO and it will work.
Single/Trade Account
Use this feature if you only want a single trade open at any time for all 10 trading robots, this is useful for small accounts or when you wish to keep your drawdown to a minimum, as the cBots do not open many trades per year, it is not often anyway there will be many trades open for all 10 cBots.
