PCM/ text message question?

[gaudet41]

I have pocket cm for my ppc6700 and it was working fine for weeks until now all of a sudden when i go to sms messaging through pcm it briefly loads the convo screen the immediately goes back to my desktop. I have also recently noticed that when I go to sprints regular text messaging, in my sent folder there is an item that says no sender and no subject. I tried numerous times to delete it but cannot. any help will be greatly appreciated.
