Sorry to hear about that.. This is a problem that randomly occurs across all third party NI libraries (not just ours) in older versions of Kontakt. Native Instruments has become aware of this and has addressed this issue in the rollout of their successor to Service Center - Native Access. Native Access is required if you're using any products that were released with or after Komplete 11 (September 2016). Please check out the FAQ and Compatibility info for Native Access before starting to use the application. Here's how to get your Library back in the browser tab using Native Access:
4 free KONTAKT drum libraries you need – and one you probably don’t. We scour the web for some unique percussion that’ll fit right into your next track. Most of it, anyway. If you’ve been keeping an eye on the Native Instruments blog, you’ve probably spotted our regular round-ups of REAKTOR freebies from our User Library. Mac: Macintosh HD Applications Native Access; Windows: C: Program Files Native Instruments Native Access; Install the latest version of KONTAKT or KONTAKT Player, if available. In the tab Not installed, find the Library that you want to set up and click ADD LIBRARY: Click the BROWSE button: Navigate to the Library folder.
1. Download Native Access. If you already have Native Access installed, opening the application will update the metadata for every Kontakt Player library.
2. Restart Kontakt. If the problem persists, please contact Native Instruments registration support and provide them with further detail about the specific library that disappears and the steps to reproduce the disappearance. Native Instruments will then investigate and update the database as needed.
If you're not using Native Access, here's the 'old fashioned' way of fixing this issue between Service Center and Kontakt (pre-Native Access):
Lightworks free for mac. When you add a library, Kontakt should create an XML file that's used to ensure your library stays in Kontakt each time you open the Library Browser. Recent versions of Kontakt have had problems generating this XML file when users add Third Party Kontakt libraries. Navigate to the following folder:
Here you will find various XML files related to the NI products on your machine. You should see an XML file bearing your product's name, such as EXHALE.xml or EXHALE 2.xml. If you don't, download the files in the links below.
Then copy the downloaded xml files to the directory listed above (make sure to move the XMLs out of the provided folder that was created when you opened the zip, the XMLs should sit directly in the 'Service Center' folder). Before opening Kontakt again, you will need to reinstall Service Center. You can reinstall Service Center by following this link and download/running the installer listed under NI Service Center:
As long as Kontakt can now find the XML files in the 'Service Center' directory, you should no longer find that your libraries are disappearing.
