Well the instructions did say to change the "00000000" several times but I'm still not sure why you're having problems. Just to make sure I tested it on other CP pages and it worked. The only way I was able to replicate your problem was when I stripped out the "Moderator" (elsif) from cp_common.pl...But I don't think that is your problem.
