i haven't had a single plugin update issue since I swore off Waves.
Knockin' on wood, though, as I'm building a new DAW and will need to re-authorize everything. The last time I went through that process, I had to let Amplitube go because it just weren't worth the hassle. Aside from that one, 100% of my subsequent plugin installation issues have all been Waves-related. I haven't decided yet whether to allow any Waves stuff on the new DAW.
