We apologize for any inconvenience this has caused. This is actually a bug we discovered with the latest version of the Product Manager.
The Product Manager will alert of a partially installed SDX sound library, even though the full library is already installed. There will be a new PM update to fix this, but we have no ETA just yet.
If you see the “ready to use” message under your SDX, then it means the full SDX has installed fine.
