Nikon D50 Error Messages

[Ronly]

I just bought the D50 and had great results for a day, then Error messages started appearing occasionally on the display. When the error message appeared, the digital image was very underexposed even though I took the picture in normal daylight. The manual suggested taking a few more pictures and if that did not fix the problem, to call tech support. It worked, but problem came back a day later. Not happy about this event.
Question 1: Did anyone run into such problems and what was the solution? (This is a new camera, so I can exchange it.)

Question 2: Are the any good Nikon Digital Camera aftermarket manuals?

I guess you should exchange it. My D50 is almost eight months old and I've never had the problem you've described before.

The only Error message on a D50 is a blinking Err
According to the owners manual this message indicates a "camera malfunction" and if it persists you should take the camera back to Nikon.
