Hi there,
When you say that
Quote: "DBPro shuts down"
I'm assuming that you mean it crashes. Is this because you are trying to directly load a Milkshape file ? Remember that DBP can only load in certain file formats.
Make sure you have the latest Upgrade 4.1
From what I know, only .X formats work well.
I have heard that people have had problems using Milkshape when they export their models into .X
Make sure that you have the correct settings before exporting.
Or as a alternative you could download a .3DS to .X converter from

As for the BSP problem, please could you please post a screenshot, as I would be able to help you more.
From what you have said it could be that your starting playing position maybe wrong and that is why things look odd.
I hope that helps ya, but please provide more information and especially screenshots help.
