Removing Plugins?

Hello. I am having troubles with Melodyne. I’m in the Plug-In information page now and I see 9 tracks used with Melodyne .vst 3 and Three instances with Melodyne .vst. Is this causing a conflict? I only want to use the .vst 3 from now on. How do I get rid of .vst. It won’t let me just uncheck it. It seems I can check and uncheck all plugs except Melodyne. I was able to uchcheck the Melodyne editor Beta. I trashed it and it still comes up. BTW, Melodyne seem to enjoy crashing Cubase after a transfer.Thanks.

If removing the .dll from the plugins folder doesn’t work, you may need to trash prefs as well.
