Your using the Jbox with a subscription to BMW`s website right? I have never done a BMW but I think you can use your tablet to download files for BMW from Autel`s servers. There is a manual on the downloads section that gives instructions for programming BMW`s. You could send a log to support and they should get back to you.

I am contacting support so they can upgrade my subscription to pro, so I can have
access to bmw files, but no replies
