Kontakt 5 "Demo" on WAV import

I wanted to mess around a little with the sampling capabilities for Kontakt 5, as I have yet to upgrade to a modern version (not the Player edition, mind you).

Any time I import a WAV file, the item becomes "demo" and gives me the time limit to mess with things before it stops.

Despite having bought Komplete 11 Ultimate ages ago, I would imagine the software I paid for should not have such limitations, right?

I would live for a solution that allows me to try some of these ideas out well before I am able to upgrade from K5 to K7.
