Thanks Bachus, although I have discovered a problem wiht it.
I bought it from a dealer in Germany, who told me it was clearance of old software. He did NOT tell me it had been previously registered!!!
So I have asked NI, if they can re-issue the serial number to me, for a fee if necessary...
Otherwise, its $320 down the drain and I throw it in the bin.
I have advised NI of this dealers name and address.
So we will see what happens.
