sorry for the late response, i haven't worked in vxace after this game so im not sure >.> It could be an issue with the RTP?? the other zip should include the whole rtp though. Maybe try the zip with "(IF YOU DON'T HAVE THE RTP)" in the title?! Or get the VXAce RTP from elsewhere (heres a link that i hope should work: https://www.rpgmakerweb.com/run-time-package)
If its not an issue with the RTP i unfortunately have no idea whats wrong as i dont work with vx ace anymore :( Very sorry to hear about the troubles, thank you for your interest
