Hello! I see that you're having trouble with ThePhotoStick Omni app. Could you please share a bit more about what exactly is not working? For example, is the app not opening, not detecting the device, failing to perform backups, or something else? Any specifics will really help me guide you better.

In the meantime, here are some initial general steps that often help with app issues on Windows 10:

1. Close and Reopen the App: Sometimes fully closing the app and reopening it resolves temporary glitches.

2. Check Device Detection: Make sure your ThePhotoStick Omni is properly connected to your PC's USB port. Try plugging it into a different port and ensure the device shows under 'This PC' or 'My Computer.'

3. Restart Your Computer: A reboot can clear up background processes that may interfere with the app.

4. Disable Antivirus/Firewall Temporarily: Some security software may block ThePhotoStick.exe from running. You can temporarily disable them or add an exception for ThePhotoStick.

If you have tried any of these or can share more specific symptoms, I can provide more targeted guidance. Would you like me to help you walk through any of these steps?
