Cubase VST for win 98

Hi. I wish to put my licensed Cubase VST for windows 98 on an XP laptop and use it briefly for some old tunes. Steinberg will no longer give me the option of swapping my printer port dongle for a soft dongle. I tried a USB to printer port adaptor, but it didn’t work (and apparently rarely does). Can anyone sell me a version with a USB dongle, or suggest an adaptor they have found that will work?
Thanks
