Hi! I’m sorry to hear that after upgrading ReadEra the app isn’t decoding (opening) your books properly. To get us started, could you tell me:

- What format are the books you’re trying to open (e.g., PDF, EPUB, MOBI)?
- Are all books failing to open, or only specific ones?
- Did this problem begin immediately after the upgrade?
- Have you tried any steps so far (like reinstalling the app or restarting your device)?

Knowing these details will help me guide you accurately. In the meantime, let me share a few quick checks you can try on your Windows 10 device:

1. Restart the app and device: Close ReadEra completely and restart your PC to clear any temporary issues.
2. Check file integrity: Make sure the book files themselves are not corrupted—try opening them in another reader app if possible.
3. Reinstall ReadEra: Uninstall and then reinstall the latest version of ReadEra from the official source to ensure the upgrade installed correctly.
4. Review supported formats: Confirm that the book format is fully supported by ReadEra. Some users have reported decoding errors with specific DRM-protected or edited files.

If none of these resolve the problem, I can guide you through more advanced troubleshooting—such as checking app permissions, reset app data, or verifying if there's a known issue with the latest update reported by other users1 4.

Feel free to share more details about your issue!

upgrade of readera will not decode any books on the app
