Sandisk Ultra 2gb sd card problem

Hi all, i am experiencing a problem when i am trying to transfer photos from the above card,

I took a lot of photos and videos yesterday at a wedding using my Panasonic lumix dmc-fx35 and when i tried transferring them to my dell laptop via a integral sd hc memory stick an error occurred saying it could not transfer the pictures. I then put the card back into the camera and it now says no valid pictures. This the second time this has happened to me, i thought it may be a faulty card but this has happened again with a new card.

Any advice is very much appreciated as the photos on the card are very sentimental to me.

Thanks

Does your camera have a micro USB port? Is there software and drivers you need to install for the camera?

Pritty sure its not the camera as ive had it for a number of years without any trouble.

I had a 32gig go bad on me.

Using the PC, I added files, then I got messages it was full.  Not.

In my SGS3, I got a “SD card not present” error about 1 week after putting it in.

Totally unusable. SanDisk replaced it.
