Creepy Crawly

I am very frustrated; the camera is playing up big time!
I put the SD card in - unlocked - and it flashes up ''WRITE PROTECTED'' every time! And now, when I switch it on, the Olympus sign flashes up, the lens pops in and out, then it beeps, flashes and blanks off. It is charged as I did that this morning, when it was working.........
Uh, so annoying, I got some cracking blips and can't upload them, hence this one I got earlier with a different SD.
