Some camera errors are due to internal computer glitches. A few things to check:

Or, if it has been more than a year since it was changed, just swap in a new one. But before you do, be sure the camera battery terminals are clean. Residues can be removed with Deoxit, or with WD-40 Specialist Elecrical Contact Cleaner Spray, either of which should be applied LIGHTLY to a lint-free cotton cloth swab. A mild vinegar solution, followed by distilled water, works too, but in ANY CASE, don't use anything wet enough to get drops of liquid in the camera, and don't spray cleaner into the camera.

If you choose to update firmware, follow the instructions VERY carefully, to the letter. Battery must be charged to 100% before you start. You will need your computer and a good Internet connection to download and unzip or unpack the firmware binary. You will need a memory card, freshly-formatted *by the camera* (not formatted in a computer!). Do not interrupt the process... It will probably take longer than you think it should.
