I had problems with my LG GT 540 mounting and dismounting the SD card of its own free will which I have hopefully solved. However now the camera won't save any of the images it takes it comes up with either "THE FILE DOES NOT EXIST" of "THE FILE HAS NOT SAVED YET". There is plenty space on the SD card and the phone gives the photo a file name in the bottom right hand corner of the image. Any Ideas how to solve this.
