Missing boxfile.yml !!!

[carlca]

Hello, I took the following steps. Created a folder C:\nanobox . I then ran git clone https://github.com/nanobox-quickstarts/nanobox-echo.git which downloaded the project from Github (including boxfile.yml). I then did cd nanobox-echo, followed by nanobox dns add local echo.dev . So far, so good. I then ran nanobox run go run server.go, which resulted in a lot of activity, including prompting me for my Windows Live password, but eventually gave the error message:

Does anyone know what the problem could be?
