you can deleted the temp files with all the cookies
or you can edited the host.txt file with notepad
is the site that great?
there is another way
open the browser> file> import and export> export the cookie to a place were you can save them to, then delete the cookie from the internet option on general tab
open the save cookie file you save with notepad then edited out the charlieoscardelta from the listing
still not 100% if it will work but it would be my short in the dark, after you edited the save cookie file click-on file> save then get out, now import it back into the browser think you be set then
