Purchased product = serial number invalid

Then I led a Ausstausch.
The new software was delivered very quickly.
These serial number is not valid.

Whether this is in the interest of the consumer, that he only has to sit with Virtual DJ in conjunction to get a valid key, I dare even to doubt.
Schaun Na times, whether the manufacturer, it gets to the number and the software still runs.

Very unfortunate for an otherwise very good product.
