Hi …, Welcome. I suggest a fresh start using **exact procedure below** : Please disable any Antivirus and firewall. Uninstall AV if needed. Use Windows to uninstall FMS Data Manager. Specifically: 1. Press Start and open Apps & Features. 2. On the right hand side, open Programs and Features. 3. Find Navigraph FMS Data Manager in the list, select it, and press the Uninstall button above. ![image](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/2X/2/2a962f42051a6f187573c47aed308baae809cff3.png) If they exist, delete folders: c:\ProgramData\Navigraph and c:\Program Files (x86)\Navigraph. Download and install latest [FMS Data Manager](https://www.navigraph.com/FmsDataManager.aspx) to the default location. Please let us know how you get on. Cheers Ian ---

Hi, please can you post a screenshot of the FMS Data Manager, with this error code … Which OS do you use? Also, have you changed something on your system (re-install OS or similar else)? Changed your Internet provider, do you use a proxy? And also, I assume, this was working before, right? Thank you! Cheers Richard ---

Hello. I use Window 11. I didn’t do anything with the Window. The program just stopped working one day. In my opinion, it should have been an airac upgrade to 2201. I was monitoring when there would be an update and was surprised that I couldn’t log in and this very error was hanging. I didn’t change the provider, I didn’t use a proxy. Thanks. ![Screenshot_4](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/2X/6/67e58f812132e757478d00b8fc602094f8287e59.jpeg) ---
