Hi hbinfo,
like Henni said : You have to copy the registrations to your Audyas harddisk !!!
They won´t work from stick.
BTW: I renamed them on PC priot transferring them to the Audya, becaus I have already registrations starting with "0001".
I renamed them to "[0200]..." up to "[0299]...].
@Henni : The styles are all in the Audya ( OS 4.2B )
