alternatively, you could download a copy of Vuescan

There is a free trial so you lose nothing if it does not work.
Vuescan supports more scanners than you can shake a stick at and, as luck would have it, the Nikon SuperCoolscan 8000ED is one of them.
You will find Vuescan here: http://www.hamrick.com
