Not getting text pictures In Handcent

[hal1]

This may have started after the 5.1 upgrade. I get this message anytime someone tries to send me a picture "Unfortunately SMS Handcent has stopped". - text come through fine. Sending pictures are also stuck in sending mode

I'm also getting the message "your apn settings is incorrect, please set it up manually" - don't know if it's related.

Receive message settings are as shown

FWIW, I un/reinstalled Handcent. Seems to be working with out going in to any settings.
