I purchased a Guitar Rig 3 Kontrol edition used on eBay. The seller faxed the required license transfer form to NI at least THREE times over the past several months that I can count. NI has failed to notify the seller the have received the form and fails to release the serial number so I can register it and get out of Demo Mode hell :angry: I have emailed NI support repeatedly... I get a canned response that looks like a bot and not an actual person instructing me to have the seller fax a transfer form... ad nauseum I mean really, what is it going to take? The seller even tried to email a signed copy of the from to NI and I have a copy of that... At this point I can only warn people... Buyer Beware..
