Building up a new rig from scratch. Mac Studio Ultra Ultra on OS 13.3.1. Libraries were activated via Native Access 3.3.1 Entered serial numbers with no issues, located libraries and NA confirmed path. Launch K5 (5.8.1) and libraries show "Activate" button on upper right hand corner in the library window. K6 and K7 does not have this issue. Same behavior in DAW or stand alone. Is it possible to drag over authorization file from old rig? I would like to be able to load old sessions with K5. Thank you!
