Hi Henni,

maybe that with AJs Upgrade something is different...

I did a clone backup of my original hd, copied it to another hd ( a different type ! ) and put this into the Audya : Anything EXCEPT the copy-protected styles was working fine.

Maybe that it would work with an identical hd type...

The ketron-usb-sticks can only be used ONCE ! On the SAME HD they can be used more than once.

I tried to reinstall the sticks as well on another hd and on my ssd, I always got the message "wrong serial number". Due to the fact that it´s still the same Audya the serialnumber of the hd seems to be the important factor.

I fully agree with copy protection, but the way Ketron does it is not the right one !
