According to and directly from Nikon:

When you see Err on the control panel, LCD monitor or viewfinder of your digital camera it refers to a camera malfunction. Try the following:

1. Remove all accessories from the camera.
2. Install a freshly charged battery into the camera.
3. If your Nikon camera offers resets such as the two-button reset or a hardware reset please follow those instructions provided in the product manual.

If these steps do not resolve the Err message we recommend having a Nikon Authorized Repair Technician evaluate the Nikon camera. Click here for repair information.

You can reset the camera 2 ways... soft reset is to remove and replace the battery. To hard reset, there is a microswitch on the bottom of the camera body opposite from the battery compartment. Youll have to reset the camera's clock if you do this. If it still doesnt work, have a Nikon authorized camera shop look at it.

Sounds like the shutter is sticking. This could be due to damage or just need cleaning. This probably means that you need to get the camera professionally serviced/fixed as shutters are extremely delicate.
