Hi Yoshi,
the reason for this behaviour is that we ran out of licenses for the Special Edition.
This is temporary, the new licenses are already on its way.
Meanwhile, you can install and operate the Vienna Instruments with the Demo Mode on your ViennaKey [:)]
Please try to register again tomorrow.
We are sorry for the inconvenience.
Thanks for your patience!
Best,
Paul
