Huh, it's weird that it's behaving for you like that. Well, that settles it. I'll upload a version that is just the game in a zip folder. Annexing the in-engine compression process.
I uploaded a version of the game that wasn't compressed using the compression software within RPG maker XP. Now you just need to do that initial unzipping that should now give you all the main game files. Hopefully that should fix the issue for you or anyone else facing this problem.
