THE1TRUEECHO'S PROFILE

I just downloaded an RPGMaker game, which has been working fine for other people as far as I can tell, but for some reason I keep getting that error.

I have no idea if I need to download and install something or not, since I have never used another RPGMaker game.

For reference, it's The Adventures of Tara: https://www.patreon.com/Reepyr
Don't kinkshame me, just help me fix this.
