MAMP & OpenDNS - Didn't play well together, now MAMP broken

MAMP & OpenDNS - Didn't play well together, now MAMP broken

My MBP 15 on 10.7.5 used to deploy MAMP locally like a dream, but after I
tried out OpenDNS (switching my DNS's to the recommended IPs), whenever I
tried hitting localhost, ODNS blocked/redirected it to a search.
Eventually, I stripped my DNS settings, and it returned back to the
default IP assigned by Comcast (10.x.x.x).
So when opening MAMP now, when I hit Start Servers, I get both green
lights. But the start page comes up, and I get "Firefox can't find the
server at localhost.", "Oops! Google Chrome could not find
localhost:8888". After about 3 hours of cold research and trial-and-error
reinstalling, messing around in Activity Monitor, modifying host files,
httpd.conf, etc. I'm right where I started.
I have no idea how to "clear" the effect ODNS had on my setup, and I have
some certainty that that was the cause, as it worked without a hitch
before. Should I abandon my efforts to MAMP (short of wiping out my
computer)? Or is there a way I can get it back working?
Appreciate your response, Stack Overflow.
