Recording lost?

Hi,

I’ve recorded a conversation with my Sansa Clip,

After I’ve finishe, when accessing the player - I caoudln’t play the file, nor any other files that were recorded earlyer (and worked fine before).

I’ve connected the player to the computer and copyied all the files to it. I could not play any of them - and also the file size of the last recording was 0!!!

What can I do?

I realy need that recording!!!

Thanks for any help
