The Root Cause of the Problem.
I have a DSC-W200 and I had the same problem as the rest of you. I found out how the problem started to begin with. If you change the "Conversion Lens" settings under "Shooting Settings 1" for your camera to either "Tele" or "Wide," this would cause macro and flash to not function properly. I hope this information will help someone. This way, you guys will not need to keep resetting your date/time and other settings you may have saved in order to get everything back to normal. Take care everyone.
