My SMS messages don't show up -- i can send, the amount recieved is right, but they dont' appear. How do i get it back!?

Heres what i did:
1) I used the RomTool to modify the rom from GSM 1.10 to custom rom with SDHC. This broke the SMS, even with the new SmartTextEngine_device.prc in rom.
2) Reverted back to original rom. SMS worked, but didn't restore backup.
3) Upgraded to 1.20, then restored backup. SMS now don't show up again.

Whats wrong?!?
