E-mail app force close problem on Samsung Stratosphere

On my Samsung Stratosphere phone, my two email accounts are linked. When I try to open or reply any email that I am seeing, I get the message: "The Application email (Process.com.android.email) has stopped unexpectedly. Please try again. And in a bar: "Force Close"
Turning the phone ON/OFF or pulling OFF the battery didn't work. Any help please?
