Pictures look crisp and clear on my computer, but don't have high enough resolution when I order prints?

I will say, however, that the image you see on your computer screen will always be different from the printed image simply because it's calibrated as a computer screen with frame rates and flickering/dithering. Still, your camera has 7.1mp resolution. That's good enough for prints up to 8x10, so I have no idea what they are referring to. Are you sure you are shooting your pictures at the highest resolution setting? It's possible that you're shooting on lower quality and as such only getting fraction of the resolution you could be.

What I would recommend you reset the camera. This is a fairly easy procedure which involves either going into your setup menu and choosing "reset," holding down the menu key for 5 seconds, or, removing the batteries for a few minutes. It may be that the firmware loading got corrupted and the camera just needs to be "rebooted," which is something that turning it on/off won't accomplish. But after which, you should have the camera reset to factory default settings.

Then, go into the menu settings are make sure your resolution is set to maximum highest quality. There's also a few other things you can do to improve your performance:

1. Prefocus. Hold down the shutter half way to get a prefocus of the image you're shooting. When it changes, prefocus again. This will speed up your camera's performance during picture taking since it won't have to autofocus before it shoots the shot.

2. Use faster SD cards. Yes, there are faster cards and it does make a difference in writing the image file to the card. This is especially key if you're taking multiple or burst images.

3. Fresher batteries. Use alkalines at least. But I recommend using high energy batteries designed for digital photography. Varta is a good brand. They are usually sold in camera shops, are long lasting (because they are sold in small quantities) put out alot of energy.

4. Shoot in "sports" modes when you're in situations that require action. Night or available light modes when in night time settings. These presets can help in speeding up your shots, rather than the camera taking a split second to evaluate the conditions of the lighting.

5. Pan with the action. You can create some pretty cool shots by panning with your shot, focusing on your subject. This will create the effect of your subject in sharp contrast to the blurry background.

6. Use a flash - even in day time. This will "freeze" the image and cause your subject to "pop" in the shot. However, flash is only designed for limited range and can dissipate outside of about 20-25 feet unless you're using a zoomable flash.

7. Stick with 100-400 ISO. Going higher will cause more noise/grain in your shots, particularly in darker settings.
