Here’s a streamlined approach:
Make Your Steam Profile Public: Go to Steam’s privacy settings and ensure your profile and game details are set to Public.
Check Internet Connection: Confirm you have a stable connection.
Update LaunchBox: Ensure you’re using the latest version of LaunchBox.
Obtain API Key: Request an API key from Steam’s API Key Request page (you don’t need to be a developer).
Reinstall LaunchBox: If problems continue, try reinstalling the software.
