Nikon Coolpix L310 Memory Card Problem?

I've had my nikon coolpix L310 for almost two months, and it had been working fine. All of a sudden today, whenever I turn it on it says "This memory card cannot be used".It's the same card I've been using the entire time.It works fine when I take it out. I'm just wondering why it stopped working all of a sudden. I checked to see if it was locked, and it's fine.

My camera creates random colored frames when animating?

I create stop-motion animation, and recently while animating I go back and review the animation by clicking through the frames and up comes a colored frame. Its like someone took a translucent colored filter of colors such as yellow or green and put it in front of the lens. If anyone has any input on whats going on that would be great!

The camera is a Nikon Coolpix L120
The setting was on Up-close or "flower."

Help with a Kodak EasyShare?

My grandpa gave me a Kodak EasyShare digital camera that he has had for like almost 5 years I think. I don't use it because I don't know how to take the pictures on it, but I have a Nikon Coolpix.In the Kodak camera there was a memory card so I've been trying to take pictures on my Nikon with it so I can print it with the Kodak (it's the one with a printer just for the camera, the Kodak EasyShare dock) but it says format unknown and stuff like that. How can I print my pictures? It won't even show the pictures do I need to change the format and how?

Why won't my Nikon coolpix s4300 charge?

Had it for about a year, but i hardly use it because i have a dslr.anyways, I wanted to charge it, but it wont charge. I used multiple chargers that fit, tried different outlets, and still nothing works. I know that when it charges, the on/off button blinks a green light, but it doesn't anymore.Im thinking it's the battery, but it cant be because it's still new (to me at least).
