I think they have too many different versions and probably should just have an "artists" version and a "pro" version.  When they offered me a side-grade from Infinite to Complete, I thought I was getting just a slightly different version than the one I was using.  It was upsetting to me that they actually had removed features and went back to the old interface.  The more I think about the the more annoyed I am--an upgrade shouldn't be a downgrade or at least it should be a lateral move, this really felt like a punishment.
