Hi there! I see you're getting a generic "error" message when trying to use the HiTV app on your Windows device. Let me help you narrow down what's happening so we can get it working again.

Could you tell me a bit more about the error? For example:
- Does it happen right after you open the app, or when performing a specific action?
- Is the app saying anything else besides just “error”?
- Have you noticed if your internet connection is stable when this happens?
- Have you tried any fixes already that I shouldn’t repeat?

If it’s just a basic error message, here’s a straightforward way to start troubleshooting:

1. Check your Internet Connection: Make sure your network is stable and working for other websites/apps.
2. Restart the App and Your Device: Sometimes a fresh start clears temporary glitches.
3. Clear the App Cache and Data: On Windows with WebKit-based environment, clearing cache might mean resetting browser data or clearing app-specific cache if available.
4. Update the HiTV App: Ensure you have the latest version installed, as buggy older versions might throw errors.
5. Reinstall the App: If nothing else works, uninstall and then download a fresh copy from the official source.

If you’d like, I can guide you step-by-step through these in detail or explore more advanced settings based on what you tell me next.

Are you able to share more details on when and how the error occurs?
