Samsung Moment :: Text Msg Error Screenshot

I first reported this error msg here I am getting this error msg while replying to a threaded txt msg it happens at random sometimes but on the average between 7-10 msgs deep. I cannot make any sense of this because if it was a format issue of how I have my contact entered then why would it allow me to respond to the msg until I get the error. I know looking at the image below you cannot see my previous replies but trust me I am able to reply to txt msg's. I will mention this I do have my line blocked so my contact entries are as follows *821732-555-5555 mobile pager 732-555-5555 <<This is the one I txt to the other number example is the one I select for when calling the person so the number is unlocked.
