I just lost a lot when I reformatted, but my fella has an external drive for his games and photography and I put my PTU tubes and a lot of sigs on there.

Only thing I can suggest with PTU is zip everything up, load em into yousendit or something similar and get them on a friends pc. I did that before the external drive..I put them all in you sendit and downloaded them onto my partners pc.

If you have your license number you may be able to get some of the tubes back, after all you have a license for those tubes. Some of the scrap places may help you too, some of them are very friendly. Other than that just let go of whats gone and start anew  As Shiela said to me..start afresh with a clean computer.
