ERROR MESSAGE

I have a NEXTEL I875 cell phone that I purchased from Ebay recently, and everything works fine on the phone except the camera. When I push the camera button, I get a error message, "MULTI MEDIA ERROR" so therefore, cannot snap any pictures. Could this be a software issue, or is there anything I can do to make the camera on this phone work.

ANY HELP WOULD BE MUCH APPRICATED!!

THANK YOU.
