We can turn on the camera, but the OK button does not wok.

Just the other day my EasyShare CX7330 started acting funny. I wasn't able to delete pictures anymore. I thought it just need a new set of batteries. So, we changed the batteries. Now when we turn it on the "update time and date screen comes on. and when I try to push in the OK buttone on either "update or cancel" it wont work. I arrows up or down but nothing else. I can't seem to find the manual online either.
