Clear Preferences (Windows)
By clearing your preferences, Mixbus can be launched as if it were a clean installation.
To delete your Mixbus preferences on Windows, please find the folder: "(home folder)/AppData/Local/Mixbus{version}"
The AppData folder is a hidden folder so you'll have to set your file manager to show hidden files or, alternatively, type in the explorer address bar %localappdata% and then hit enter.
Please drag the folder to your desktop (or just delete it). Then re-launch Mixbus. This will create a new, empty preferences folder with the default settings. You will have to re-add your VST plugin paths and re-scan your plugins.
