I have reset your bandwidth but wanted to explain a bit more about how this works:
The bandwidth limitation refers specifically to your usage of Box "share links" in a given month. Once a free user reaches 10GB your content can no longer be download via shared links until the next month.
(Our business and enterprise accounts are capped at 2TB per user.)
Hope that helps but please let me know if there is anything else I can do to help. And thanks for using Box!
