A couple of thoughts. You added a 1 gb card. Do you have an "old"
card? Did you try that? Or, can you try it with another card, either
new or a friend of yours.
Have you tried formating the card from your computer's card reader?
I don't know about Kodak, but with my Canon dSLR, the first thing it
does is check the card. If it finds a new operating system, it
immediately asks you if you want to update your operating system from
the card. That is how you flash the RAM or update the operating sytem.
If Kodak is the same way, you might want want to try to "upgrade" the
operating system. It sounds scarier than it is. If you can do that,
it might reset everything.
