Just in case, could you and Formbank try this:CraddyMusic wrote: ↑Mon Sep 06, 2021 8:31 pmI'm experiencing the same problem. Absolutely everything waves have been rendered useless. I've spent the whole day trying to install older versions. VST2, VST3. None of them work.
1. Uninstall FL Studio 20.8.4.
2. Delete the FL Studio folder (by default: c:\Program Files\Image-Line\FL Studio 20).
3. Reinstall FL Studio 20.8.4.
4. Run the program.
5. Click Options > Manage plugins.
6. Rescan and verify all plugins, including previously verified ones.
7. Open a Waves plugin in a new and empty project.
8. Tweak any control on the plugin.
Then let me know what happens.
