I had a similar problem with 4 styles, 2 of them from the pendrive 2011, 2 the audya internal, I said style corrupted, and what step without I know how it is that is had erased the hard disk and not appeared in ketron Spain tried to send me them but as they were not the originals from my Flash drive did not work and I have lost them because I am not going to buy a new pendrive. I still think that this should work otherwise pendrives anti-copy system.
