I've been wanting to format the lappy anyways...I just got it and HP had all their crap loaded onto it...been wanting to do a nice clean XP Pro install on it (it had Home on it)... but it seems my XP Pro disc is at my other house haha...doesn't look like I'll be exploring the new SonicStage tonight... Maybe someone else here has time! By the way, I don't think you need to reinstall windows for the Japanese language pack...just go into the Control Panel, Regional and Language, language tab, then tick the box for East Asian language support and it'll install them...but since I don't have my XP disc here, I can't install them haha. I think after installing those supports, you can then install the SS Japanese software (might have to set it to Japanese in the first tab first)... If anyone else explores this, let us know your results! -Derek-
