Hi, I'm thinking of upgrading my Komplete 12 standard to 13 standard. 2 of the products in 13 I had already purchased separately slightly exceeding the upgrade cost available to me. If I decide to go ahead and purchase the Komplete 13 upgrade am I correct in thinking I can sell the 2 products I already purchased? If I can sell them on what is a realistic percentage of the original cost to ask? Cheers, Mark (MoJo).
