EastWest Play 5.04 problem

[Googly Smythe]

So, I've just installed this update - now none of my projects that use it, recognise it. I get a "vst not found" error.
It's like they changed the id, because when I insert the new version, I can still load the presets I've saved and all is fine. Same when I start a new project - saves and loads ok.

Anyone else with this "feature"?
