It is showing me a memory card error & can't take pictures or download the ones in it. So I bought another newer memory card & used it for one month & everything was working fine. Now again the same problem is showing up again, Mem Card Error & I can't take any pictures anymore?!? What should I do?

First, remove the card, and look in the slot for any bent flash card pins. If you see any, don't fret, it's possible that you can fix this yourself. See this article on how to unbend flash card pins.
But if no pent pins are seen, then the camera's clock battery has worn out, and is likely causing this problem. Unfortunately this battery is internal to the camera. But Canon will fix this for you (for the S400 only) for free, with free shipping. Please see the Canon advisory for your camera here.
The internal BIOS battery has run down and is causing this error. Don't attempt to fix this yourself. Canon will fix this for you for free, with free shipping, regardless of your camera's warranty status. See and print out the following advisory:
The clock button battery inside the camera has expired. Canon will fix this for free (or if you want, will send you a replacement battery with instructions on changing it out). Read the following recall advisory, then contact Canon at 1-800-OK-CANON:
I would give this software a try: http://www.download.com/VirtualLab-Data-Recovery/3000-2248_4-10610841.html?cdlPid=10801131 and be more vigilant about backing up your pictures. Flash memory can corrupt at any time. Good Luck.
On the old Powershot S400, this error was caused by a dead internal "clock" button battery. Fixing it required simply replacing the battery. But before you attempt to do that, would first suggest trying a different memory card.
Hi momincali - I posted a solution for someone that seemed to have the same problem as you. If you didn't see it, this is what I wrote:
I had the same problem on my PowerShot S400 as well as I couldn't reformat the compact flash
when using the feature on the camera. The solution that worked for me
was reseating a small battery (about the size of a watch battery) in
side the camera. To get to it you have to take the case apart. I found this solution by googling and typing: powershot S400 E50 error I'm not sure if this site will allow me to add the web link - but this link had a picture of the camera and where the battery is located. http://www.pinoyhack.com/2006/09/14/canon-powershot-s400-fix/
I decided to try it, since I figured I had nothing to loose, becaues otherwise I'd be looking for buying a new camera. To my surprise it
fixed my problem, but I do not know if this is a permanent fix. If you do try this - take note of where each of the screws come from. There were 4 different size screws around the case.
seem to be a lot of complaints about this problem though.
Canon will fix this for you for free. It's an inherent fault with the S400. It has a little internal button battery that causes the problem as it gets old and run down. Check this website for more info. Look for the bright/bold yellow post describing how to return to Canon.
1 set date to 31-12-2030 23h59 and switch camera off.
2 wait two minutes, day will be 01-01-2003 and camera asks you to set the date
3 take away memory card
4 set the date to today
5 insert memory card again
Now your error should be solved.
