Challenging Driver Hunt!

OK, so at work someone donated an old Creative Prodikeys keyboard+keyboard which is handy for doing music composition on the computer. As you would know it Creative is not known for making good drivers, and their support for those drivers is even worse. I am trying to find a driver that will work with it under Win7 home premium 64bit. From what I understand there were no official Creative driver made for this product in 64bit, but someone made one that worked and use to be available for download at proaudiosoft.com, but it is not there anymore.
I know it is a long shot, but if anyone has any ideas I (or more specifically my wife) would be grateful!
 
Good thinking, I think I could get that to work.
next problem; the website only has an update driver, which requires the original driver to work... as this was donated it did not come with the CD, and I cannot find the original driver anywhere. Any chance you could host it somewhere for me? Or at least point me in the right direction?

My wife saw the keyboard and is stoked about the idea of not needing her midi keyboard to do composition work anymore, I'd hate to let her down now.
