Hello, I have had this error message for months after I transferred my files over to an ssd. The browser is also showing that I have a BAT balance of zero even though I had some before.
What I have tried: Uninstalled and reinstalled brave. Restored my account. These did not help the issue.
Current Brave Version:
Version 1.17.73 Chromium: 87.0.4280.67 (Official Build) (64-bit) Windows
Any help would be appreciated.
Thank You
Brave browser is currently in the version 1.21.77 I think,so first thing you should do is update your browser.
Go to settings/security then make a check then the browser will attempt to update himself (I think that are the steps, I’m not at my pc at the moment and I not remember clearly 
)
Thank you for your response. I was able to solve the issue.
The problem was that the brave browser was not updating correctly. I had this error:
Cannot update / install Brave - Error 0x80070005
I followed the guide provided in the link below the error message and it solved the problem.
Thank You again for helping me fix this.
