Compaq Ipaq question - I can't explore the device!

I just got a Compaq Ipaq and I am trying to copy at E-book. I’ve opened my active sync on my PC and clicked on the Explore button but it doesn’t show me the documents in my device like it should. I just opens the mobile device and has a blank area. I have been searching forums online to see what the problem is and can’t find the answer anywhere. It’s making me nuts! Anyone know what could be wrong?
