The Universal Audio website claims that it would cost $50 if you are upgrading from the previous version, which makes buying the software over easier to be okay with but I'm being charged $150 as the 'Sale' price.
Upon doing more research I find out that I'm being forced to purchase Auto-tune Advanced, which is 'BS' and an 'FU' to customers who spent their money on the software.
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.
