Did you try running "Root Checker" from the market? Your phone must be rooted 
and DroidWall just runs "su" to acquire root, so there is not much I can do if 
that is not working properly...

I have an LG Optimus V. Droidwall was running fine but after upgrading 
Superuser, Droidwall, and some other apps it has stopped getting root access. 
Every other root required app is still working and I see Droidwall in 
Superuser's accept automatically list. Having seen comment 1, I installed root 
checker and it verifies that I have root access. I can't figure out why every 
other app still works.  Though, droidwall is the only root app in Superuser 
with a command different than "/system/bin/sh".
