If you have the button at the top named Library, right click on that, and select Switch/create library, then in the dialog box that pops up click on the little blue folder on the right and navigate to where your library is. Leave the first option checked, Use the previously existing library ...

That's how I do it, because I don't keep any personal stuff in c:\users\hobnail or c:\documents except settings and whatnot that apps create. (I put my personal stuff in \home\hobnail.) Then there's no need for me to worry about migrating my c:\users or c:\documents stuff when I upgrade or replace my system since I know to make a backup copy of \home before I do the upgrade/replace. Of course I lose all of my app settings, but whatever.
