You;re not going to like this answer, but if your RI is gone, it's gone. You're going to have to restore it from scratch. In the future, when your dbc is where you want it to be, run GENDBC (installed by VFP under the \tools\gendbc subdirectory for VFP) and save the PRG it generates. This PRG can be used to restore such things in the future.
