Can't receive MMS anymore?

[dave52355]

I have a xv6800 flashed with RM 2.2 Heavy and running on cricket. All was well until the past 3 days. I can get on the web no problems send and receive text messages and send pictures. But I can not receive picture messages anymore. I have reset the phone, checked all the settings, *228 but nothing seems to work. Wen a picture message is sent I get notification that there is incoming message but after a few seconds it just disappears.

Before I reflash the entire phone and have to reinsall my apps can I reinstall a cricket cab file? Or is there an easier solution?

Thanks
