How can I delete ended campaigns and add a new one? Thanks
Those boxes with the message "this campaign has ended" are just notifications or reminders. They don't affect how many campaigns you can run at any given time. Once the campaign on a route has ended, you're immediately able to create another campaign in its place. So, while it can be rather annoying that there's no way to make those messages go away, they're not doing any harm, and they do disappear after a certain period of time. Feel free to start new campaigns as soon as you like after the previous ones' ending.
Well, now its works, but there was a problem to add a new campaigne.. thanks
