it is mainly about the silent subliminal plugin, which I installed properly (and had used before already), but actually many plugins are not to activate. I clicked on “all” and “activate” and “ok”, but no error message appears, nevertheless they stay deactivated.
Even installed the earlier version to try, but this had the same outcome.
The plug-ins that are greyed out in the menu have been enabled. The menu items are greyed out because they are not real-time plug-ins. You need to select some audio before you can apply them.
