Need Help. Stuck in MDI mode.

Hi.

We have a Hyundai Kia 21skt with fanuc oi-tc. Everything was working fine until a program got to a certain block that it refused to do anything on. Had to stop the spindle zero return and now I can't execute the program at all. I can't change to another program. I can edit three other programs in background but vanity load them. I can run mdi commands and the turret rotates and moves on a and x axis. I can't edit the foreground program. It's as if the machine thinks it still needs to finish where it left off on the currently loaded program but it won't do anything.

Thanks.
