Have you tried resetting your camera? Powerdown and take batteries out. Then hold "power" button for 30 seconds, release and repeat couple of times.

Did you format the stick using the camera
if not then try that there seems to be a
problem when formatting with reader

This is probably THE most common failure among digital cameras. There's a halfway chance of fixing it yourself, described here: http://camerarepair.blogspot.com/2007/12/fixing-lens-error-on-digital-camera.html

Try squeezing the camera very hard or slam the camera in your hand as hard as you can, this usually fixes it.

e:91:01 is a flash error you might fix it by initializing the settings of the camera but there is no guaranty.

1.turn the unit on
2.press the menu button
3. select setup
4. inside setup and search for setup 1 (option with a toolbox icon with a number at the bottom.)
5. inside setup1, pls select initialize and reply with OK to evety prompt(using the center button)
6.if succesfull(you'll get clock settings)
7.set the date and time then try the camera again.

if this does not work.... call sony cust service 1800-222-7669

Please try with the new memory stick. Regards, Arpi

1. If the camera can not focus on a subject, or can not determine the appropriate exposure setting, the camera will beep and disable the shutter button. This is to avoid improper processing of the image. This is usually due to either poor lighting conditions or movement. 2. The camera Flash Element requires ten seconds to recharge between images. Although the camera is ready to continue capturing images almost immediately in bright (daylight) settings, if you are using Flash photography the Flash element will need to charge between shots. If you try to take a picture before the Flash is charged, the camera will beep and disable the shutter button. Once the Flash unit is fully charged (10 seconds), the camera is ready to continue. 3. The batteries may be running low. LCD Display, Flash, and Playback use much more power than taking pictures. It is possible to quickly consume battery power, even if you are not taking many pictures. Try turning the Mode Dial to the OFF position to recycle power. If the camera beeps and will not take a picture under normal conditions, you may need to change batteries.
