Use Program and features to uninstall "Repeater" (x64 or x86)
To preserve user data, our un-installers will not remove some files from your computer. Occasionally, these files can cause problems when updating to a newer version of the plugin. We'll need to manually remove them to see if they are causing the problems you are experiencing.
Go to \ProgramData\D16 Group
If you have created user presets, make a backup of them and delete the Repeater folder.
NOTE: The ProgramData folder is hidden by default; if you can't see it, go to Folder Options > Advanced Settings and select "Show Hidden Folders."
