Smart and Friendly quietly went into bankruptcy almost three years ago. So there is no more support for for your labels from them my friend.
There was a 3-1/2 floppy disc that used to come in some of the Smart and Friendly label packages. The program was called the "Smart and Friendly Custom CD Label Software." I used to have this disc, but sadly do not have it anymore.
Also there was support in the Adaptec Easy CD Creator software that came with the drives way back when. But since Smart and Friendly went under, I don't think Roxio (which now owns Easy CD Creator) is supporting these labels. Besides, I could not in good conscience recommend Easy CD Creator to anyone..... worst of the CDR soft out there. Plus, you would have to use a 3 year old version..... even scarier
Perhaps someone knows or has a copy of this soft still?!
BTW, have you tried to compare the labels to any modern labeling systems? It is possible that Smart and Friendly emulated a template used by another company like Sure Thing or Neato (2 of the older labeling systems still in use). Sadly, I cannot remember how the S & F labels looked like to compare.
