If you don't have the SD card reader installed in your computer & you have a USB port (2.0 preferable) you can buy a plug in reader that will read about any type of card you have.
I got one that also reads the HC cards and I think it was around $20.00.
Here are a couple of samples: Media Card Reader
or Multi-Media Card Reader
