New Post: BROWSE field under Ref. code

Hi
I have been using NB Store before, and now I'm installing the latest (new/not upgrade).
Under the ref. code in Product detail page there is a field and a Browse button.
I actually don't know why it's there, because downloadable products is not activated.
I have been looking in all flags, but cannot figure out, how I move this field.

I'm a little in a hurry - can anybody help me?

Per
