Super apologies for this! I'll look up my files and replace the RTP very soon!
In the meantime, try the GameJolt version HERE. If you install it somewhere new, you should be able to copy and paste your Save files and keep all your progress. Until then, I'll get this updated post-haste!
UPDATE - I've uploaded the correct file needed "Wind.ogg". I don't know why the RTP didn't include it. Just place it inside the Audio/BGS folder located where you installed the game. Sorry for the inconvenience this caused you!
