OK, so I panicked. However, I didn't want anybody to be caught unawares.
It was my "personal" fault. Not the fault of FPI EditPad, nor the fault of FPSC as I was beginning to suspect.
Here's what happened. I archived (moved)
all of the Scripts to the Archive Library. There were none left in the FPSC library. Then I created a segment room and some ground and a door that needed the "dooruse.fpi" script. So, I restored that script to the FPSC script Library. But, it didn't work. No "press enter" hud nor would it open when I pressed enter. Remember the
ONLY script in the library is the "dooruse.fpi"
Can anybody guess what fpi is missing that would cause this to not work? Yep, you guessed it. It is the "appear1.fpi" that is missing. So I restored that fpi and it now works. Horray. Although, there is still one more fpi missing. It is the "destroy" ai which in this case is the "disappear1.fpi" script. It will still work and open, however, if the door is destroyed it will not disappear like it should because it needs the script.
So, this is a lesson for myself as well as for us all.
Be sure that we have all the fpis required for the execution of the level/game.
