I also don't need this product and just installed it because i got it free and by time i will test it, but now i disabled the annoying plugin.
While Melodyne is bundled with Mixcraft, it is developed and supported by Celemony. Bottom line, if you want to use the plugin and keep it updated, you'll need to create a Celemony online account.
Seems IMO to be a small price for such a great plugin, but if you don't agree, just uninstall it.
FWIW the plugin is not "faulty", as many of us are using it without any problems. It looks to me like your version just needs to be updated, but again, that's your decision to make.
