Getting an error having just installed release 4.2.1 on Windows 10. Each time I try to sync it gives me an error: “Deleted sync.lock, please restart sync if no other clients synchronizing”.

Hi @phobos512

I’m sorry to hear about the issue with the latest release of Codebook for Windows, I would be happy to help. Are you syncing with a cloud provider such as Dropbox or Google Drive, or are you syncing over local WiFi?

Hello @phobos512

Would you mind logging into the Google Drive [web interface](https://drive.google.com) and navigate into the `Zetetic` folder, then into the `Shards` folder. Do you see 1 or more `sync.lock` files present? If so, and if you don’t have any other Codebook clients currently syncing, would you delete those files and then try your sync again?

I deleted them and it seems to be proceeding without giving an error now.

Hi @phobos512

Thank you for your follow-up, we are happy to hear removing those files allowed the sync to complete! We are investigating the issue here locally to determine the cause and then will work on a resolution to address the issue in a future release.
