I had a game I was working on but the RooL is missing and broken, I tried to copy the file, delete the DEGUB note and go redownload it but I failed (I backed out of redownloading)

How can I fix the original file without losing work? It won't let me go back in to actually fix the problem. I don't know what happened, it was doing so well before!

You posted this in both the Quest forum, and the QuestKit forum (which is now used for Quest 6).
Which engine is this game for? And what's a RooL?
