Hi Cecil, not problem at all, I opened both, the BBW.LST file version 2010.5 of which fortunately I have backup and the current 2011 BBW.LST file. I use notepad but you can use your favorite text editor instead. Once there you will see first on top a serie of guidelines and tips about how add and designate categories and styles to the list, followed by a long serie of the styles list and descriptions strings, a huge one in my case. It is relatively easy to find the corresponding text lines of missing styles sets, then copy and paste in the target file. After that don't forget to rebuild the style picker list.

For a deepest modification can be better (and easier) to use a more advanced text/string editor of file compare utility. Hope it work for you too.
