How to fix the plugin error caused by upgrading to Waves Central v10. If you haven't bought a plugin before June 10, 2018. You don't need the upgrade(or update). If you did, you need to uninstall all of the upgraded plugins in Waves Central v10. You need to download the legacy version from here https://www.waves.com/downloads#older and watch the video. Thanks for understanding. Let me know if this video helped in the comment section.
