Yes, this works for lower leagues, I got Bath to the premiership with it who start in BSP but as they are newly promoted side they have a BSS quality team. You obviously wont be able to get the players the filters will erccommend but keep dropping the stats until players start appearing and pick them up.
i cant download em neither :/ another mirror would be awesome
EDIT: found a way of doing it! i havent tested the files, but i guess they should work.. im going to sleep now. anyways, go to the download link, click download now (a new window will open) DO NOT close old window, once error 404 comes up, close the error 404 window and now right click the "download now" button on the old window and click "save link as...", now you can download and save the filters wherever you want!
EDIT2: nvm.. it doesnt work.. it downlaods the files and all but when i try to import em game says it cant import them
