By connecting the camera to a computer with the provided USB cable,
images on a card can be transferred to the computer. Some OS's (operating
systems) may need a special setup when connecting to the camera for the
first time. Follow the chart below. For details on the procedures in the chart,
refer to the “Reference Manual” on the CD-ROM and the “Software
Installation Guide” (included in the CD-ROM package).
Identifying the OS
Windows 98/98 SE
(Second Edition)
Windows 2000
Professional/Me/XP
Mac OS 9.0 - 9.1/OS X
*OS 8.6: See below.

Connecting the camera to a computer using the provided USB cable
Installing the USB
driver for Windows 98
Confirming the computer recognizes the camera
Downloading image files
Disconnecting the USB cable
 

Even if your computer has a USB connector, data transfer may not function correctly if
you are using one of the operating systems listed below or if you have an add-on USB
connector (extension card, etc.).
● Windows 95/NT 4.0
● Windows 98/98 SE upgrade from Windows 95
● Mac OS 8.6 or lower (except Mac OS 8.6 equipped with USB MASS Storage support
1.3.5 installed at the factory)
● Data transfer is not guaranteed on a home-built PC system or PCs with no factory
installed OS.
You can view images using: graphics applications that support the JPEG
file format (Paint Shop Pro, Photoshop, etc.); Internet browsers (Netscape
Communicator, Microsoft Internet Explorer, etc.); CAMEDIA Master
software; or other software. For details on using commercial graphics
applications, refer to their instruction manuals.

I don't think you need the disk, this is a hardware connection issue, not a sofware issue so we can take some troubleshooting steps to try to get your images downloaded. I will just need a bit more information from you.

SOURCE: Transferring photos

Had exact same problem. Here the solution:
Choose playback, then "Mode" button will bring you Slide show options menu. Navigate to Image/Sound Copy Item.
You'll find options to copy from/to internal memory/flash card there
