I may buy Komplete Kontrol S49 mk1 second hand. I want to know, if the person refused to deactivate their registration, can I still send in the serial number and receipt of purchase, and therefore get the software that was originally included? If so, does that mean I get KOMPLETE 11 SELECT with no additional cost? From what I understand, so long as I have proof of purchase, NI should make me the registered user and I get that software for free, right? Also, if I want to upgrade to Komplete, can I pay for the upgrade to Komplete 11? Or is it only possible to buy Komplete 12 now? If the latter, then how much do I have to pay to do that - I guess that may be classed as a 'crossgrade' + 'upgrade'? And if it's a lot cheaper to upgrade from Komplete 11 Select to Komplete 11, rather than 12, and if 11 is not for sale on the website, where can I get the upgrade to 11 (not Select) at a good price? I could not find this info on the website so I'm grateful to be advised here! Many thanks.
