From the Canon-Europe Consumer Products website:
Errors in image playback may occur as a result of the following problems.
・Image format is unsupported
・Image data is corrupt
・Image was edited or renamed on a computer
・Image was shot with another camera
・Image was written back to the camera without using CameraWindow*
* CameraWindow is software used to import images and change camera settings. You can install CameraWindow from the bundled CD, or by downloading it from the Canon website.
Try another SD card and see if you get the same message. Most likely the memory card is corrupt and needs formating or relpacement.
