Hello and welcome.
The game was updated a day ago. When games are updated, they tend to break trainers.
We don’t take update requests in the forum. Here’s how it works: Game Queue - WeMod Support.
And in the interest of keeping the forum tidy and posts easy to find, please make sure you read and post in the trainer’s official forum thread in the future: Northgard Cheats and Trainer for Steam. Clicking the “Discussion” button in the trainer takes you to the trainer’s official thread.
Thank you and have a great day.
