I have a Brookstone digital picture frame that stopped working

When the unit is powered on.. the status bar looks like it completes it cycle and then the screen displays a large INSERT MEDIA
display. Which is interesting because I have my pictures loaded in their memory. That message INSERT MEDIA is not even mentioned in the little users guide. When I insert the SD card it doesn't recognize it either.
The SD card is good. !!
When I connect the frame to my computer via USB, I can view pictures that are in the frames memory.. and downloaded a few more pics
but I can't get the frame to get past the innsert media display..
