http://knowledge.seagate.com/articles/en_US/FAQ/215451enYou don't need to reinstall Creative Audio Center. I had issues with previously released drivers, But finally the issues seems to be fixed with the new Realtek Audio driver! I installed the new driver, Creative Audio Center Recognized it without any problem and I launched all programs above with enabled Subwoofer boost and no more lock up!
plz let me know, works for me and many people.
