Joe, ask Elaine to tell the shop ASAP that the disks aren't working. Many places will keep your data for a period of time after a transfer to disk then delete it. If it's after that, it's gone. If not, they should be able to make you a different set of disks. Your drive in your machine, does it say DVD or CD on it? If it's a CD and they've given you DVDs for instance, they won't work. Other than that, the disks may need to be remade. Does the disk I sent you work in the drive?
I'm glad you're sill on the mend.
