I've downloaded the BB's Database Desktop, and installed it on my PC as well, but the problem is that the built-in Help section is in the German language which makes it a little bit hard to understand. I recommend downloading it, then use Google Translate to translate the passages to see exactly if the table restructure is available.
Obtain the software from the following link: https://sourceforge.net/projects/bbdbd/
In the installation folder(
C:\Program Files (x86)\BBDBD) you will find the bbdbd.chm file that contains all the information you need.
