Doubtful. I have never WUPPed myself, but have been eventually "upgrading" all along. It's been rocky for sure. But I must say, the latest version of the Waves Central now includes a bunch of the "helper" apps and fixes for legacy versions. So (knocks on wood) it has been going pretty well lately. Not sure when I last bought a Waves plugin though, but I have been grabbing their freebies...
