Do keep in mind that piracy or piracy of film is illegal, and sites like TodayPK are streaming pirated videos. To avoid being banned, such sites often change their domain extensions. So, if you can't get into TodayPK, then that's probably because they have changed extensions. Do not worry, though, because often, even if you type an old URL, you will be redirected to the newest live link. Otherwise, you might want to Google the new one.
