Restore a library
To restore a backup of a library, go to File > Library > Restore Library and browse to the library you want to restore (it will be a .zip file). You may have to restart the program.
The automatic Library backup .zip files are stored at a location set in Tools > Options > File Location > Program Files > Library Backups. Manually created backups are stored at the location you chose in File > Library Back Up Library. See Backup Library.
Note: Use restore to load a backup of a library. If you want to simply load a different library, see Load a Library.
