Does anyone know why Tubetrack (see

There's a now a new version of Tubetrack available that fixes these
problems, though anyone who's used Tubetrack in the past few days will
know this as the program prompts you to download the updated version.

I hadn't used it until I read this post. It's a useful tool to have.
