Renpy won't launch my games - common file errors and trying to read the other game's script?

[Preseva]

I've been working on two games: The Miller's Daughter, and a little side project called Kingdom Adventure. I'd been working on Kingdom Adventure for a few days, then last night tried to launch The Miller's Daughter, and it makes it to the title screen for a few seconds before crashing. The same thing now happens when I try to open Kingdom Adventure. I'm flummoxed.

Here's the traceback when I try to open The Miller's Daughter. The audio file it can't find is a Kingdom Adventure audio track, and the bottom of the traceback says "Kingdom Adventure." The errors in between look like they are pointing to Renpy's generic files. (The "D:\0 Miller's Daughter" folder in the traceback is the folder Renpy is inside. The projects folders are inside Renpy's folder.)

Here's the traceback that happens when I try to open Kingdom Adventure. Again, it looks to me like the problem is with Renpy's general scripts:

I've deleted and reinstalled Renpy but that hasn't helped. Older versions of the games aren't working, either. I didn't do anything weird or different from normal when this bug happened.
