6600 stuck on sending message

I was sending a multimedia message, and cancelled half way through, now it seems stuck in the outbox, says its deffered but now always has the sending arrow on, and battery only lasts a day.
It wont delete, send or move to drafts folder. It seems to be a 1kb file that wont budge!
I've tried finding it with file explorer and deleting it, I've deleted the original media message, I just can't find where this 'ghost' file of a text is hiding.
Can anyone help? I'd rather not reformat the whole thing if I can find and delete this file.


Cheers :sad:
