Have you considered talking to Kingston - if you have the receipt and can prove it is YOUR data, they may be able to help.
Whilst not publicised I'd be surprised if there wasn't a way to release the rest.
Can you get them to give you the software again, there again many of these drives come with a tiny CD on which is the software and drivers for Win98.
If you've only deleted the icon, the program should still be installed on your computer. Have you tried to go to the installation directory and look for the exe program?
