...Did you check the the Waves plug-ins are not in the Waveshell and assigned in the correct VST Plug-in folders?
They are in the Waveshell (sorry for not knowing the correct terms, that's what I meant by "compressed" - there are just two DLLs in the VST folder). VE 5 seems to get along with the Waveshell and gives me access ot all my Waves plugins, VEP 6 not anymore. VST plugin folder (64bit...) has the same path in VE 5 and VEP 6 settings.
