latest win32 binary of snort

Hi,

I've got the latest win32 binary for snort along with the current ruleset.
"C:\Snort\bin>snort -V
-*> Snort! <*-
Version 2.0.0-ODBC-MySQL-WIN32 (Build 72)"
and snort rules stable from "Mon Jul 14 20:19:07 2003 GMT  Works for 1.9.x  "

I'm having difficulty getting the 'established' rule to work for the 'flow' keyword. The current porn.rules file 
contains;
alert tcp $EXTERNAL_NET $HTTP_PORTS -> $HOME_NET any (msg:"PORN freeXXX"; content:"FREEXXX"; nocase; 
flow:to_client,established; classtype:kickass-porn; sid:1310; rev:5;)

however if I remove the established, then the rule alerts for pages containing FREEXXX? can anyone point me in the 
right direction to what might be causing that.

The init output is posted below;

Cheers

Tom H
