my first advice is always to delete your cookies and temporary internet files . that seems to work most of the time .
flash cookies are kept seperately , so you need a special tool to remove them .
http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager07.htmlgo there and scroll down until you find smaspower.com in the list , then click the button that says "delete website"
or you can just delete all your flash cookies at once with the "delete all websites" button . flash cookies aren't god for anything anyway .
