Nkit processing of Nkit Wii file

After downloading Nkit and the associated DAT files, I downloaded a Wii file in Nkit format. Since that file was missing a partition, it kept failing the ISO expansion. I understand that for missing partitions, one needs to download the FULL NKIT version which is 14GB. Yikes! Unfortunately, the WBFS version faulted as well in SHA-1 checking in WiiBackup Manager. Double Yikes! Anyone have any better way to get the ISO version?
