It appears SampleTank 4 is not recognizing the Library file install. Let's try the following to fix it:
- Open SampleTank 4 Standalone
- Go to SETTINGS > Sound Content
- Remove all the directories shown there
- Click on Rebuild Database
You should see it all empty.
- Now restart the app
After restarting, SampleTank 4 will look for the install paths. This essentially resets where SampleTank 4 "looks" for library info.
This might work.
