The Mac and PC VST3 versions of Auto-Tune Artist (and the previous version of Auto-Tune Live) are unfortunately not cross platform compatible. In other words, Auto-Tune Artist settings saved in a project in a Mac VST3-compatible DAW (Cubase, Ableton Live, Reaper, etc.) cannot be opened by the PC version of Auto-Tune Artist in the same DAW (and vice versa).


For example, if you save a project with the Mac VST3 version of Auto-Tune Artist in Cubase, you will not be able to load these Auto-Tune Artist settings in the PC version of Cubase because the Mac and PC versions of Auto-Tune Artist are incompatible with each other. The same holds true when migrating VST3 Auto-Tune Artist session data from PC to Mac. This also applies to any DAW that's compatible with the VST3 version of Auto-Tune Artist (and Auto-Tune Live).
