Hey there, at first THANK YOU for this mod!
Sadly, after I updated to 1.3.1. the mod doesn't work anymore... sort of... I have the modified .dll and the new toolbar, but when I open the AFBW window, it's just blank grey with a cut-off "Settings" text in the corner. I uploaded a screenshot: https://www.dropbox.com/s/a69yvefj5luy9y8/afbw.png?dl=0
