Message stuck in Outbox

[Keir333]

I have a message that's stuck in the outbox of my text messaging and keeps resending itself over and over again. When I go into the text messaging Outbox folder and try to delete it, it asks me if I am sure that I want to delete the message....I click 'yes' and the message still remains in the Outbox. The person that the message was originally sent to is getting pissed at me cuz they think that I keep sending this message over and over again. Does anyone know how I can stop this message from being stuck in my Outbox? Is there a certain folder in the registry that I can go into to delete it from there? Thanks for any help anyone can provide.
