You probably have a corrupted UFS library file so you can try these steps:
- Open UVI Workstation in standalone
- Open the Browser by double-clicking any Part (or the eye icon at top)
- Right-click the related library under the Soundbanks tab
- Select Verify soundbank integrity
If the library appears as "Invalid", please download the product again until it succeeds.
You will find download links to all your registered products on the My Products page.
