The DLL should work fine with BUG, but the DLL by itself doesn't do anything you can see. You also need to merge in the changes Blacksun made to CvMainInterface.py to BUG's version of that file.
Both BUG and Blacksun modified the same Python file, and for both to work, you need to merge both sets of changes into one new file. If you are using the normal scoreboard -- not the Advanced Layout from BUG -- this shouldn't be too hard.
Since this mod shows you hidden information, we won't be including it in BUG.
