Ah, it's fine. As you said, the error seems to be related to an issue with RAM or perhaps the RPG Maker engine itself, since it occurs after the game has been running for beyond 8-10 minutes (some games I run will slow down or experience a drop in performance after some time has passed due to a lack of available RAM). 

I ran the game again, and the screen froze on the transition for a couple of seconds before, oddly, transitioning to the normal battle scene for around 3 seconds before it froze and cut to black. Music and sound still played.

While I was playing through the demo, I encountered an error where during the transition between the dialogue to the battle sequence, the screen would be stuck in one state for around 30 seconds to up to minute and then go to black. This seems to always occur on the second time the battle sequence is loaded, and it happened twice while sparring with the boy in the castle garden and once in the forest during the encounter with the Terror, in which this error message came up after the battle. While the screen was black and unresponsive, the game wasn't, and it seemed like I was able to still attack, use my skill/magic, and defend. The sounds of the attacks and what I assume were death sounds still played. All other programs were operating normally while this was happening. I have a fairly low-end laptop with 4 gigabytes of RAM, so it could just be my laptop unable to run the game optimally.
