Computer not recognizing Sansa Fuze - SOLVED!

So,

I would try this, but there is absolutely no sign that my Sansa is plugged into my computer, except for the fact that IT says it’s connected.

I have a Windows XP, I have Windows Media Player 10, I have NO sound card, ummm… what else?

Now, I know my Fuze does work, cuz i’ve taken it to school with me and put music on it, but at my own computer it doesn’t even show that there is a “Mass Storage Device” or any such thing connected.  

It’s driving me nutz.

If anyone has any suggestions as to what to do, that would be grand.
