Hi there! I'm really sorry to hear that you're having trouble sending messages on Talkie. That can be frustrating! Let's work together to fix this issue.

Could you tell me a bit more about what happens when you try to send a message? Do you see any error messages, or does it just not go through at all?

In the meantime, here are a few general troubleshooting steps you can try:

1. Restart the App: Sometimes, simply closing the Talkie app completely and then reopening it can resolve minor glitches.

2. Check Your Internet Connection: Make sure that your Kindle is connected to the internet. You might want to try switching between Wi-Fi and mobile data if that's an option.

3. Clear App Cache: Clearing the app's cache can sometimes help. Go to your Kindle settings, find the Apps section, select Talkie, then press 'Clear Cache'.

4. Update the App: Ensure that you have the latest version of Talkie installed. You can check for updates in the app store.

5. Reboot Your Device: A simple reboot of your Kindle could also help refresh the system.

Let me know if any of these steps help, or if you need further assistance!
