sansa m200 setup

I bought my sansa player refurbished, so it came with no software. When I plug it into my computer (WINDOWS XP), the setup wizard pops up and at one point it ask to insert a disk for set up. But when I bought the item it didn’t come with any software. Where can I get the software for free. Can I get it from you or can you recommend a website I can download it?

Any help would be very much appreciated
