I thought everything was fine and I come to realize that the version of Auto-Tune I bought is no longer being supported. When the previous owner transferred the ownership the instructions asked me to update my software so I could register and authorize my plugins.
I bought a second hand Arrow because I wanted something portable while still having access to my plugins. I used it on my Twin when I owned it and on my X6, which I own now. I've been using Antares Auto-Tune Realtime pretty much since it became available.
