I recently re-install Sony Vegas Edit 16.0 on my Pc (due to a bug, i had to uninstall it) and since this "reboot", each time I start my Pc and open the program, it want me to insert my key product...
It's not a dangerous situation but its kinda boring...
Thanks in advance for your answers (and sorry for potato english :/)
In other words, set's advice is that you should try "to deactivate a device so you can activate a different one, go to your MAGIX account > My Products > Show More Details > Deactivate." (FAQ item 9)
