Hello lightspeed! Well, I'm certainly not one of the guys, but I have a few ideas;
If you don't have your old computer available, you could try the dvd on your wife's computer to see if you could get everything in there. If you are able to do that, just transfer those jpg, midi, mp3 or any of those files that you have into a usb flash drive, memory stick or similar, and tranfer them do your new computer.
If you have your old computer available, the usb sticks could do the trick as well.
Note, sometimes cleaning the dvd could change things.
Good luck!
