If your PC is not old you do not need a disk to access the SD card. It will show up as a drive on Explorer. Another option is to purchase an SD card reader and eject the SD card and place it in the SD card reader.
If you really do need the FujiFilm Software try this link: http://www.fujifilmusa.com/support/ServiceSupportBrowse.do?prodcat=878931&sscucatid=664260
If it is the CD for your Pc you require I can only tell you mine came with the camera in the box and I think that you can probably download it from the FujiFilm web site. If it is the Flash card you are referring to then you can buy them on line from Amazon or any camera shop. I still think it is a lousy camera. I decided to buy a Cannon SLR but it cost me about £1000.
