I tried installing this mod, but it doesnt ask me where to put it or what to change. And after I used it, there were no changes to the game atall. How do i know if its working or not?

Baldurdash is a collection of differing fixes, and you do not say which version you tried to install. Here is a direct download to Baldurdash WeiDU 1.68, which is for SoA and will install via WeiDU.
