Cannot change Tunespan location to backup of crashed HD

I had a hard drive go bad -- the one where all of my spanned files were located. Fortunately, I had a backup. I successfully restored my "Tunespan iTunes" folder to a new drive.

I cannot get TuneSpan to work with the new drive's "TuneSpan iTunes" folder.

I followed your directions here (https://randomapplications.useresponse.com/topic/moved-spanned-media-directory-to-a-new-drive). The new location shows correctly.

But when I follow your directions that say "Then, just click Span and TuneSpan should find all the files in the new location and just quickly update the locations in iTunes TuneSpan gives me a message that there is not enough drive space on the new drive.", TuneSpan tells me there isn't enough room on the new drive (there's 60GB in addition to all of the previously spanned media files). iTunes cannot find the files to play. And TuneSpan cannot find the files.

What to do? Nothing I've done seems to work. Very frustrating, and I feel like I'm missing something despite thinking I'm following your directions exactly.

Thank you!
