N4 and N4 Player use a large number of files to work: emulation presets, dictionaries, skins, temporal files, etc., and in the case, a file is wrong or corrupted, there is a lot of possibilities that N4 or N4 Player stops working completely or crash your host (DAW or NLE). To avoid complex problems we recommend deleting all the files and reinstalling the latest N4 or N4 Player version available and the problematic library using always using the latest Aquarius Desktop application version.

Remember that N4 and N4 Player cannot coexist on the same computer or operating system.

Please follow these steps:

  1. Close your host (DAW or NLE).
  2. Download and install the latest Aquarius Desktop application version and run auto-update to the latest version.
  3. Back-up manually your N4 (or N4 Player) content.
  4. Delete your N4, or N4 Player, content altogether, which means you should delete manually and completely the N4 repository folder (the N4 repository folder is a shared resource folder for all N4 plug-ins formats), and the N4 plug-in files completely from the plug-in(s) folder(s).
  5. Install N4 (or N4 Player) from the Aquarius Desktop application.
  6. Run N4, or N4 Player, on your host (DAW or NLE), and check is not crashing.
  7. If the problem is related to a specific library or emulation preset. Install it again via the Aquarius Desktop application.
  8. Run again N4, or N4 Player, on your host (DAW or NLE) and check the specific library or emulation preset is not crashing.

NOTE: Try to replicate the wrong behavior in a new session, do not use old sessions or old templates.

For problems related to third parties libraries and emulation presets that are not for sale in the Acustica Audio web-shop, you should contact the seller or developer of that library or emulation preset directly.

In case of continuing problems after following the steps above you should provide help-the following information.
