Fanuc R30ia will not start in auto

We swapped a robot arm yesterday, keeping the controller in place. We can't get it to start in auto. It is set to start on UOP, mode other with the appropriate routine 'main' selected. UOP 1,2,3 and 8 are on. We get the UOP 6 start signal, but the robot does nothing. The teach-pendant says "paused", no alarms. It runs the main routine in manual without an issue.

Any suggestions would it could be?

Thanks id advance.

Found it. Somehow the UI signals were set to False.

Thanks for the suggestions anyhow.

Thanks for posting solution. It is always good to know.

Not posting solutions is my biggest pet peeve!
Also, I am getting much more involved in robots than I used to be (basically just did touch-ups so far), so I probably post a lot of questions on this board and want to start out with a good impression
