I could not remember how you get the new serial number. Sorry, i know this has been covered many times, but i looked in the support section and could not find it.
i don't have the new GPO yet, this is the second edition and the kontakt player has been updated 2.24. GPO activated okay, but I get the error message from the service center that i have the wrong sn for the KP2. I think i recall you have to get a new sn??
...and i just had a thought, if i have Kontakt 3, should i use that sn??
