Hi there! I understand that you're having trouble opening the Vanco app to make your church contributions. I'd like to get a bit more information to help you better.

Are you using the Vanco mobile app on your phone or are you trying to access it through a web browser on your Windows 10 PC? Also, when you try to open the app, do you see any error messages or does it just not respond?

In the meantime, here are some initial steps we can try:

1. Restart the Device: Sometimes, simply restarting your PC or mobile device can resolve app loading issues.

2. Update the App: If you're using the Vanco mobile app, please make sure it’s updated to the latest version from the Microsoft Store or relevant app store.

3. Check Internet Connection: Ensure your device is connected to the internet reliably since Vanco needs network access.

4. Clear Cache or Temporary Files: On Windows 10, if accessing via a browser, try clearing the browser's cache or try a different browser such as Edge or Chrome.

If you could tell me the device you're using and what happens when you try to open Vanco, I can guide you through more tailored steps.

Does that sound okay?
