Resolving an issue on a Windows PC can be complex, given the wide variety of possible configurations. Here are some basic steps to check:

1. Check the app version
   • Make sure you have the latest version of the application.
     The version number is displayed at the top right under the cogwheel icon. It will appear in red if your version is outdated. If you don’t see it, your version is very old. To update your app, follow this link and click the “Get it from Microsoft” button.
     
2. Check your Windows version
   • Your system must be Version 10 (build 1809 – 10.0.17763) or later, 64-bit (x86_64). See the prerequisites in the FAQ section of our website for more details.
     
3. Try another network
   • If you are connected to your home Wi-Fi, try using mobile data sharing (hotspot), or vice versa.
   • If you are on a corporate network, make sure you are not behind a firewall that could block certain data (such as coastlines or weather data) from loading.
   • If you use a VPN, disable it.
     
4. Restart your PC
   
5. Check our Facebook group
   • Visit the Navimetrix Users Facebook Group to see if other users are experiencing the same issue.

If these steps do not solve the problem, your PC may not be compatible due to insufficient RAM or a graphics card that does not meet the app’s requirements.
