Default TILT with Dutty's WM6.1 and no signal

Hello there you xda geniuses! I need a little help... I have an ATT Tilt running Dutty's WM6.1 WWE radio 1.65.14.06 protocol 25.81.40.02w. I bought this phone with this ROM, so I don't know what all was done to it, but the problem I am having is that from time to time, the phone and data switch off to 'no service' and i cannot get a phone signal to register, unless i soft reset it. I have read of this on several lists but cant seem to find the definitive answer - do i need to flash the ROM again, or with something other than the version it uses in order to get this resolved? I am missing calls and messages when it is down. Please save me!!
