Your design failed to convert properly from an older version of Libero IDE.
Libero IDE may have been unable to locate old design files. Or it may have been unable to copy existing design files into the local project directory.
Make sure that Libero IDE has access to your existing design files when it opens.
Import your project files manually so that they are copied into your current project directory. You must first open the ADB designs that failed to convert. To do so, double-click the files in the Libero IDE file manager. The Audit Settings dialog box appears and enables you to copy your files to your local Libero IDE project folder (click the Copy locally button). When you are finished copying the files locally, Save your design to complete the conversion.
Your design may still be using files that are not part of the current Libero project. Libero IDE attempts to convert your old design files each time it opens.
