Are you on a laptop?? I haven't had this problem, if your on a laptop or mac, it could be a bug.
If not, then it's entirely possible that you have a corrupted download or piece of it that might be causing the issue.
You may want to try and down load again and try all over, and see if that's what's causing it.
I'm not much on technical help, but that's what I would do. If it comes out with the same results, then I would post it as a bug report.
It's possible, that another Brother here has run into the same problem and can guide you better than I.
Sorry I can't be of more help Brother...…………………...Peace!!
