Hi, Klor, is this the professional version or the standard version, do you have a link to the product page?
The problem with your email not working will not be related to the cTrader cBot's warning messages.
If you are using the Neptune trading cBots, turn off the News Release Manager option if you have not yet installed and started the News Manager cBot, please read below for possible causes.
An error is caused when the news manager feature is turned on in the cBot, but not configured in the news event manager cBot, you can either set up and start the news manager cBot or turn the news feature off in the Neptune cBot.
Let me know if this fixes the issue.
