I don't have any experience with your particular situation. But I did have a problem once with compiling the game. In this case, the problem was caused by I difference in the code of the editor when compared to the code of the main game. First I played the game, then I used the editor, the editor compiles, and things mess up.
So basically, did you change the code of the main game? Did you change the code of the editor? If so, do the changes have an impact on the functionality of the other code? If so, did you change the other code too?
If this was not the case, I cannot help, but I do wish you good luck with your difficulty.
