When Audiobook Builder presents a -128 error, it means there was a problem reading the disc that's being imported, usually because the disc is dirty or damaged. iTunes can often handle iffy discs better because of its error correction feature, which forces repeated scans of a damaged area until at least something is pulled off, so you did the right thing by trying the iTunes import. The -2048 error you received later when dragging the files from iTunes into Audiobook Builder can occur for a number of reasons, though. No matter the case, we can surely help with getting everything back up and running smoothly again but we’ll need to gather some additional information to determine exactly what all is going on behind-the-scenes as the errors occur. Could you reproduce the issue and then, just after, generate a System Information that will include some extra background logging? The report can be saved by launching ‘System Information.app’ from Applications/Utilities and then choosing ‘Save...’ from the File menu at the top of the screen. Send the saved report over to us at
support@splasm.com and we'll have a look.
