firebird's ab'er didn't quit working because he gave up programming,
for one, he didn't give up PROGRAMMING, he gave up on the neopets cheats and such
also, he was forced out of it a week ago and the ab'er worked just fine until today when they changed the code, it your copy is still working it just means you are using the old version where it just checked to see if you were logged into neo via internet explorer
you can definately tell a former nhacks member by the constant insults
