Hi there! It sounds like you're having trouble with the SEPTA app freezing when you try to enter your credit card information. Let's work together to find a solution!

First, can you let me know a bit more about the situation? Are you receiving any error messages when the app freezes, or does it just become unresponsive? Additionally, could you confirm if you've tried using the app on a different device or if it's always been on the same one?

In the meantime, here are some general troubleshooting steps you can follow:

1. Clear App Cache: Sometimes, app caches can cause issues. If you're able to do so, try clearing the app's cache. This may help by removing any corrupt data that could be causing the freeze.

2. Reinstall the App Again: Since you've already uploaded the app three times, I recommend uninstalling it completely and then reinstalling it from the official app store. This ensures you're getting the latest version and any potential bugs from previous installations are removed.

3. Check Your Internet Connection: Ensure you have a stable internet connection. A weak connection might contribute to the app freezing while trying to process data.

4. Device and OS Compatibility: Sometimes, certain apps may not perform well on specific operating system versions. Since you're using Windows 10, ensure your device's system is updated to the latest version.

5. Try a Different Input Method: If the problem persists while typing in your credit card information, consider trying to paste the information instead of typing it directly, or vice versa.

If none of these steps work, we may need to look into deeper technical support. Would you like me to search for specific issues related to the app freezing during credit card entry? Let me know how you'd like to proceed!
