Can't create or send new text message

[walter17]

For some reason, when I select the "New" tab on the Messaging screen, it takes me to a screen where I'm asked to select text message, my email accounts, or SMS/MMS. When I select "Text message", it takes me to a listing of all my text messages, but when I select "New", it just hangs up with "Text messages" replacing the "Start" logo on the top left corner. Neither new nor "reply" to any of the messages work. I've performed multiple soft resets. Any help would be appreciated.
