Casio EX-Z700 not recognised on Win XP Pro

Hi,

I wonder if anyone can help. I have a Casio Exilim EX-Z700 camera that I've been using quite happily on a PC. I recently bought a secondhand PC but this one won't recognize the camera at all.

On my previous PC it came up as a removable drive. On this one it tells me the hardware was not installed because the wizard cannot find the necessary software.

I've checked the manual and XP should just recognize the camera as a drive.

I've tried putting the XP disk in, no joy. I've checked the disk that came with the camera and the only drivers are for Win98.

I've tried searching the net but there are no drivers for this camera, not even on the Casio site.

Can anyone tell me where I can look next to sort this out?

Thanks
