I tried looking for the same driver/firmware.
My daughter had the same unit. Warrany expired. I contacted the manufacturer and they advised that there is a Canada wide recall on the unit! They instructed me to bring it back to the store and exchange it for a comparable unit.
The person's contact info at the manufacturer is as follows:
Kelley Sellers

Thery replaced mine with a Creative Zen Stone - great little player.
Hope this helps.
