If the error occurs in MyChat Client for Windows, and you can't update the server for some reason, then follow these steps:


  1. Shut down MyChat Client.
  2. Extract the latest database backup (ZIP archive) of a client application from the folder C:\Users\%USERNAME%\AppData\Local\MyChat Client\backup\ into the folder C:\Users\%USERNAME%\AppData\Local\MyChat Client\db\, by overwriting files. This backup is created automatically each time when updating the client application.
  3. Install the older version. Download it from the lobby on your server.
  4. Launch MyChat Client.
