Not redirecting (looking to redirect to a member home page)

Hello, I have WPMU set up, but only one site running -- a nonprofit site that will have members-only info on a separate member home page.

I installed Login Redirect, activated it on the site, set the member home page url... and nothing. Login works, but redirect does not.

I tried: 1) variations in the redirect URL; 2) network activating instead of local; 3) sacrificing a chicken to the WP gods.

What am I missing?
