There is free software available (I'll try to find the source now) that you can run to retrieve some if not all of the data. I'll get something on it and post later. Ijust googled and found this. Don't know how good or bad it is but maybe worth a shot.
Tesco do a real cheap USB card reader which could get you out of the bind of not being near a machine that has a SD card reaser. €5 or €6 if I remember correctly. In fact I had a look at the Tesco uk site just there and they had a Technika 16 in 1 Memory Card Reader for just £2.50 so keep an eye open in your local store - it may be that cheap here too.
