Bought a new memory card and camera wont read it

Make sure your new memory card is an SD card. If it's larger than 2GB then it's actually an SDHC card. While it fits into the slot, an SDHC card will not work in devices designed only for SD cards.

This error message means that the card is corrupted or formatted for another digital camera. Turn off the camera. Insert a new card or format the card.
Try to format the memmory card using a card reader and the PC this should solve your problem if not you have to replace the memmory card.

The S200 uses SD cards. Your new 4GB card is actually an SDHC card and will not work in the S200. You need to use SD cards, 2GB and smaller.

Did you check the write protect tab on the card?

To rule out a faulty card, format it in the PC using a card reader.

Older C310s won't take that large a card. Try to exchange it for a 1 GB or smaller. I had the same problem - a PNY 1 GB works fine

power on camera press menu button scroll to setup menu push ok scroll down to format press ok scroll to memory card press ok and you done.

Have you tried to format it with the camera? It may need formatting in order to unlock it.

this camera will only take up to 2gb

the problem might be with the slot of memory card, if the same memory cards are working in another phones than consult with nokia care, they will be able to sort out the issue for u.
