Hey guys, I'm pretty new to the whole Kontakt-Business, but after spending several days on google, trying to figure out how to solve my problem, I ended up on this forum. I bet there's a very simple solution to this problem since I'm very new to this. First of all something to my configuration: 27" 5K Retina iMac, 10.10.5. OS X Yosemite, 4GHz, 32GB RAM, AMD Radeon R9 M295X 4096MB I'm working with the latest version of Logic Pro X. Talking about my problem: 1) I'm creating a new project - create a new instrument, add Kontakt Player, everything's fine EXCEPT that my Kontakt player is completely empty. Every library I added in previous sessions is gone. So everytime I open up a new project, I'm supposed to add every single library again. 2) Everytime after finishing/saving the project to my hard drive and re-opening it a moment later - Logic says "Kontakt 5 - Loading instruments has failed, as the library "Signal" is not installed on this computer" (which isn't true). So... right now I can't work on a project more than 1 time, because Kontakt is always "forgetting" my instruments (and so do I). I really hope someone can help me out on this since here are a lot of experienced users/moderators. Thanks in advance, I'm grateful for every trick/hint. PS: and btw. I already tried to do a "re-batch save" but nothing changed my situation.
