Hi there! I understand you're having trouble with making a payment in the MovieBox app. Let's get this sorted out together. To help me assist you better, could you please let me know:

1. Are you trying to make a new payment or renew a subscription?
2. What exact issue do you see when you try to pay? (e.g., error message, app not responding)
3. Have you tried any steps already, like restarting the app or checking your internet connection?

Meanwhile, here are some initial steps that often resolve payment issues with MovieBox on Windows devices:

1. Check your internet connection to ensure it's stable.
2. Close the MovieBox app completely and restart it.
3. Clear the app cache and data:
- Go to Settings > Apps > MovieBox > Storage.
- Click on "Clear Cache" first, test the app.
- If that doesn't help, also try "Clear Data" (note this may require you to log in again).
4. Make sure the app is updated to the latest version.

If you’re still facing the payment problem after these steps, it might involve more advanced troubleshooting or account validation.

Could you share the exact error message or behavior you observe when trying to pay? That will help me give you the next best steps.
