Go to this link http://code.google.com/p/better-oblivion-sorting-software/source/browse/data/boss-oblivion/masterlist.txt (each update is at the same link)
on the right where it says File Info, theres another link View Raw File
Click it, wait until the page refreshes, then right click the page and choose save as
save it as masterlist.txt
copy to the usual place boss saves the masterlist. (Currently in Oblivion\Data\BOSS\ folder - Heads up ; I think thats going to change when BOSS 1.7 gets released, but thats a while away yet)
Note: Windows by default does not let you see filename extensions, to change this go to start, control panel, switch to classic view and choose folder options, view tab, and in the list un-check Hide extensions for known file types. Click okay.
If you had extensions hidden, and you saved masterlist.txt, you would actually be saving masterlist.txt.txt
Annoying. Also deceptive - You can download what you think is a picture for example...
fluffybunny.jpg <<-- a hundred spaces here -->> .exe
Double click it and you get more than you bargained for
