2. 3V lithium batteries use to fail while showing good. Silver oxide and alkaline are more reliable. I have not kept up with the battery technology so the failure may be moot.
3. when the film is loaded, back closed, turn the rewind in the direction of the arrow until it becomes snug. Now as you advance the film the rewind knob should turn opposite the arrow.
4. take the lens cap off.
5. Are the frame numbers and film type visible in the edges of the blank film? Yes - film loading or other camera problem. No - improper processing.
6. bad camera.
