Wow something I just learned about flash has its cookie type that is
NOT cleared when you clear your cookies or cache. I may have been a bit slow to finding this out so thought to share the knowledge with other players. Firefox has you covered with this add-on
https://addons.mozilla.org/en-US/firefox/addon/6623
You can also find the files in the Application Data directory of Adobe Flash directory name is #SharedObjects
something like this
X:\Documents and Settings\Saint\Application Data\Macromedia
This is used for ads and other things so read up on it as something are needed
